[Bug 914311] [NEW] vt.handoff 7 breaks psb_gfx driver

[Lucazade]

Public bug reported:

When using a gma500 based netbook with psb_gfx driver (shipped by default with kernel => 3.x)
if the option "vt.handoff=7" is enabled (by default) the psb_gfx driver cannot initialize itself correctly ending up in a blank screen instead of X. 

I believe the KMS part of psb_gfx is not able to create the framebuffer
and use it on VT7 with the fbdev xorg driver.

Removing vt.handoff=7 settings from grub (temporary or by editing
/etc/grub.d/10_linux) the system load correctly.


if necessary I can provide further info, let me know.
