[Bug 542536] [NEW] nouveau kms vt switching broken

[Vishal Rao]

Public bug reported:

Vt switching broken with or without the xorg-edgers PPA. apparently
happened during the time nouveau was backported into the kernel instead
of being a separate module. Problem occurs even without plymouth etc so
it looks like just a nouveau/drm issue. Works (meaning KMS is disabled
so flickerful vt-switching works) if I set "nouveau.modeset=0" in kernel
boot parameter.
