You would think ATI's steaming pile of crap would be a good reason for 
them to give up on the whole binary module thing and just release specs so 
someone else can write a decent driver.

I made the mistake of purchasing an ATI X1600.  No open kernel driver.. no 
open X driver.  The ATI drivers don't even complile on amd64 on any 
recent kernel and their X drivers are prone to random screen corruption 
that requires nothing less than a full reboot to clear.

IMO let those morons keep writing themselves into a corner with this crud 
and then perhapse they will see for themselves that binary modules are a 
horribly bad idea instead of having someone else to blame when this whole 
thing finally fails.
