Last time I played with nv & rivafb (a loooong time ago), I found out
the hangs were caused by some weirdness with the manipulation of the
endian flip register and got that working. The problem I've been working
on for restoring console is different, and has to do with forcing a
call to set-par when coming back from KD_GRAPHICS mode. That is already
upstream (though I noticed some X driver still mess with the HW after
the switch back, like the radeon one)
