Title:
  vt.handoff 7 breaks psb_gfx driver

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  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.
