Actually, for the older drivers ATI had this special program where
people could write open source drivers for their cards after signing
an NDA. The overall crappiness is due to the fact that 1) ATI doesn't
invest much resources in linux development and 2) they can't tie into
the kernel so tightly as the DRI folks can (because of licensing
problems). Although that's just a guess
