Firstly I too have a long list of profiles here: CrogramDataAdobeCameraRawCameraProfilesCamera
For Pentax cameras the selectable options available on my machine are
Adobe Standard
Camera Standard
Pentax 1.00
Embedded
ACR 3.7
ACR 4.4
Adobe standard is the default profile, and the one that I use most of the time. As I understand it, when I open a RAW image with CameraRaw or Lightroom, the program reads the exif data and loads the camera specific version of Adobe Standard.
So for example if I open a RAW image captured with a K10 CS5 would use this file CrogramDataAdobeCameraRawCameraProfilesCameraPentax K10DPentax K10D Camera Standard.dcp which it would call Adobe Standard
If I were to open a RAW image captured with a K7 then this is the file that CS5 would use CrogramDataAdobeCameraRawCameraProfilesCameraPentax K-7
Take a look when you open a file you should see something like Pentax K10D - IMG6421.PEF at the bottom of the CameraRaw window.
Camera Standard is I believe an interpretation of the customised in camera setting used to display (on camera) and output JPEGs
Pentax 1.00 is a generic profile that was probably created by Pentax, but which I believe not been updated since its relase several years ago.
The ACR profiles are throw backs to earlier versions of CameraRaw and may not be available if you did a clean install.
The Embedded profile I know little about, but assume that when selected it preserves any ICC profile that may have been embedded within the image.
Finally for information purposes only, if you browse the directory of your hard drive you might find several files relating to one particular model. That is because Canon and also Nikon developed multiple profiles for some camera models.
I am sure others will come along to correct any errors, but I hope this explanation provides a general idea of how camra profiles are applied.

Suppose the easy answer is to always shoot raw and do this adjustment in camera raw ...
Lens profiles are something entirely different and their purpose is to correct recurring problems of under/over exposure, vignetting, CA and distortion, that occur with a specific camera/lens combination.
Lens profiles tend to be camera specific , hence you will see the camera model and lens in the name. If I leave the program in auto detect it will quite often pick a K20D lens profile, as they seem to more available than K10D lens profiles and are possibly the closest match.
Lens profiles are generally created for adjustment of RAW images and that is why there will not be many available, if you are processing a JPG. That said some people have created JPG specific profiles. I am not sure if it is possible to create combo profiles (RAW/JPG), but on my system if I open a JPG with the auto detect option enabled a DA 17-70 is selected.
There are quite a lot of profiles that can now be downloaded from the Adobe website and they have created a free of charge download program for that purpose. There are also lots of user created profiles around , which can easily be found with a google search. Be aware though that not all profiles are created equal and the profiles in the last update were provided by Pentax and as such are my preferred choice.

With reference to your comment above, I can see that the menu in CS5 is filter / lens correction, therefore the fact I cannot choose the camera model from the drop down menu is irrelevant as it is just there to narrow down the search items to get to the right lens ? As you say, the profiles were profiled on raw images so may not work correctly on jpg. It is also a slightly different interface and does not have the nice wee sliders for manual adjustment.
Okay, think I have it straight in my head now (as much of a headache as learning layers !).
AS I normally shoot raw anyway, use the lens correction in camera raw and forget about the CS5 one.
Thank you. Now, anyone have a profile for a 100mm DFA Macro

Is it the camera (K20D) that is not supported ?
Someone please help, otherwise tell me it's a poor feature that I don't need anyway !
