[Nouveau] Kernel module fails to initialize on AMD751 based system with NV34

[Clemens Eisserer]

Hi Younes,

Thanks a lot for taking the time to reply to me mail.

Updating the Bios (latest version for that board was Dec. 2000) didn't help.
I also tried nouveau with an old TNT2M64 card, but that didn't succeed either:

Should I file a bug directly against nouveau instead Ubuntu/Fedora?


Thanks again, Clemens
