If you didn't already do it this way, can you mount debugfs with nouveau loaded (i guess you may need the patch already mentioned), and copy the VBIOS image from /<debugfs/dri/0/vbios.rom for me please?

I worried with this option because when running lsmod command the "nouveau" driver is present, but I could not see traces in dmesg.... As a work-around, we also tried unsuccessfully to blacklist the driver (rdblacklist=nouveau kernel boot parameter). Using the nouveau.disable=1 kernel boot parameter prevents the driver to be loaded, but its a side effect (error on no "disable" option in the driver). Is there a clean way to blacklist it ? Thanks again.

Otherwise, there are some attachments in #43029 that might help, including dmesg output from Knoppix 6.7.1 with the above-named card.

According to observation and dmesg timestamps, the kernel appears to go out to lunch for about four minutes. Later, when attempting startx, keyboard input becomes extremely unresponsive, and video output is blacked out. This is with kernel 3.3.8-desktop-2.mga2. The same installation and kernel work well with an ENGT430 card. What information (dmesg, Xorg log) would be useful?
