Its got its own memory, not shared. Thats its about only strong point
(and that it can be made to suspend dri quite easily although my
patched has seemed to be ignored on dri devel).

AGP x2 means it is capable of doing AGP at twice the speed the first agp
bus had. I think new systems are up top x4 or x8 but x2 is still not
that old.
The proprietary drivers from ATI don't support this cards only the much
stronger firegl. It does need the CVS dri drivers from the mach64 tree
since there are still security issues with them so they weren't merged
yet into the main dri tree (they are in the process though with an
accompanying warning).
