Not this this answers your question, but I can say that this card works
with vesafb by passing 'vga=834' to the kernel-- I do that on a laptop
with the same chip.  But if I enable the frame buffer using this method,
I can't use the radeon driver in XFree86.  But, the radeon driver isn't
stable enough for me so I don't mind not using it.  Haven't tried
XFree86 4.2 yet though (or radeonfb for that matter).
