Nouveau - May 2011 - G73 [GeForce 7600 GT] - nv41_sgdma_backend

Hello,

I got a report from an AROS user that his current card (mentioned above) 
has problems in 3D with nouveau - very slow rendering. After some 
investigation it turned out the problem is usage of nv41_sgdma_backend 
for this card. Once changed into nv04_sgdma_backend card works correctly 
again.

The error(s) reported with nv41_sgdma_backend is:

[drm] nouveau vm flush timeout: 0x00000022

The card product id is 0x0391

Please let me know what other information is needed.

Best regards,
Krzysztof
