Radeon FB in 2.6.0-test4 fails for me

[Peter Chubb]

Hi,
	On a Clevo laptop with a Radeon Mobility M7 LW (AGP), enabling
	the Radeon frame buffer results in an unusable LCD display (as
	if the horizontal and/or vertical sync were incorrect -- lots
	of skewed diagonal lines)

The kernel log shows this:

 radeonfb_pci_register BEGIN

With FBDEV disabled in X, I see this in Xfree86.0.log:
