DRM on nForce chipset

[Marc Santhoff]

Hi,

before i start swapping the mainboard of my computer I'll try one last
time:

Has anyone managed to get hardware acceleration working on a nVidia
nForce based mainboard?

I'm talking about an "Epox 8RDA+". Grafics card is a MGA400, but this
makes no difference, I think.

dmesg (partly):
