Bug#740953: [xserver-xorg-video-nouveau]: No devices detected. (anymore)

[Markus Huber <markus.huber@yahoo.de>]

Could be the VBIOS problem which upstream is adressing on their website:
http://nouveau.freedesktop.org/wiki/TroubleShooting/#index10h3

Adding the follwoing kernel boot parameter solved the problem on my laptop 
with kernels 3.13 or higher:

nouveau.config=NvBios=PRAMIN


The error message I got when booting without this parameter was:

nouveau E[   VBIOS][0000:05:00.0] 0xc581[ ]: unknown opcode 0x00
nouveau E[ DEVINIT][0000:05:00.0] init failed, -22
nouveau E[     DRM] failed to create 0x80000080, -22
