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.
