Actually, turns out this is a simple problem (the vt switch one). The FLIP_CNTL
bit will not get set. This has to do with that while X sets up the
CRTC_OFFSET_CNTL register we're relying on drm to set the flip cntl bit, which
it will only do when a new client dispatches a flip.
Not sure how exactly a good solution would look like, since we don't save any
regs when LeaveVT is called (only when using fbdev, which indeed saves that reg
just for page flipping). Probably just saving those offset cntl regs when
leaving vt might do the trick (though I think a solution which would also get
rid of the FLIP_CNTL bit when page flipping is not enabled would be better).
