Hi fellows,

As Adrian mentioned "vt(4) is my baby now", so you can try HEAD on
revision more or equal to r264259, that can fix resume with vt_vga and
textmode=0.
But if question related to drm or Xorg, there I will not be able to
help.

You can ask some question related to modern, KMS aware, driver for Intel
to kib@ or related to Radeon to dumbbell at .

Thanks!

WBW
