Title:
  vt.handoff 7 breaks psb_gfx driver

Status in The Linux Kernel:
  Invalid
Status in grub-gfxpayload-lists package in Ubuntu:
  Fix Released
Status in linux package in Ubuntu:
  Invalid

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.

  + tried nightly iso image and already tried mainline kernels.

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