cold hang on mixing "nv" and "radeon" on amd64

[Mikhail Teterin]

Hi!

I'm trying to use a PCI Radeon with an AGP Quatro in my single-CPU
Opteron machine.

Calling `X -configure' as well as just `X' (after hand-crafting the
xorg.conf) locks the machine solid...

The last things on the screen are X-server messages (by memory):

	(WW): MEM alignment corrected <some addresses>
	(WW): IO alignment corrected <some addresses>
	(WW): MEM alignment corrected <some addresses>

Is this a fixable amd64-specific problem, or do NVidia and ATI cards
just not mix? Thanks!
