I was never able to get cgminer to find the ADK and, as a result, can't see fan and temperature info from within the program. I can see it by querying the ati driver directly, though, so I have been able to keep track of everything.
If you look in the source directory, cgminer's configu looks for the ADK header files in ADK_SDL so....
/cgminer-3.0.0/ADL_SDK/
Should have something like:
adl_defines.h adl_sdk.h adl_structures.h readme.txt
then a configure --enable-adl should find it.
