[linux-2.4.9-ac10 PATCH] ATI Radeon VE QZ framebuffer support

[Nick Kurshev]

Hello!

I want suggest still one a little fix for radeonfb.c driver
for latest Alan's Linux distribution.
After study of XFree86-CVS code I've found that Xfree86 doesn't
differ VE QY and VE QZ chips from driver point. So I guess
that my code will work correctly with VE QZ chip. Finely -
in the same way as with Radeon VE QY chip.
Also I've added Radeon Mobility identificators but these chips
require volunteers for testing and improvements.

Best regards! Nick
