/usr/X11R6/lib/Server/drivers/ati contains some headers and source code
for the ati driver.
I only know that because of having trouble with the cvs version killing
the intel 815 card.
I looked at the debug rpms on one of the mirrors and saw nothing related
to xorg-x11.
I haven't coded for years and then only simple "hello world" arena
programs. I couldn't advise you on coding much.
Running the query file option for rpm shows that xorg-x11-sdk is
responsible for that directory.
rpm -qf /usr/X11R6/lib/Server/drivers/ati
xorg-x11-sdk-6.7.0-6
This is probably the extent of what I feel can help you out. You might
have luck with the CVS version of X that is available in the development
directories on the mirrors.
Good luck,
Jim
