OK, I'm probaly showning my dumbness but...
I've unpacked a tarred file with drivers for Radeon graphics adapters.
All the files are either .c (source code) or .h (headers for the source code).
In X11R6/lib/(can't remember off the top of my head the full path), there are what seem to be the drivers for all the currently supported graphics adapters.
These end in .o
If this where make and configure come in?
