[Nouveau] [drm] failed to open device

[Dmitri Sosnik]

Thanks! Yeah, something strange here, lsmod shows nouveau module as
loaded, but there is nothing from nouveau in dmesg, just one line that
drm is initialized.


I am booting kernel with nomodeset parameter, so efifb driver is used.
When I am trying to boot with nouveau I am just getting black screen
(system is available via ssh though) and dmesg says:
[drm] Initialized drm 1.1.0 20060810
