Also, from the linux suspend mechanism, /usr/lib/pm-utils/sleep.d/99video is
just useless or breaks more than it helps. I just removed it. It tries some
weird workarounds that are not beneficial, and the driver (once corrected)
should work without those. Instead, you can place the above into
sleep.d/99video plus a bit of glue logic to run it on resume. This *almost*
works, i.e. I do get a working display, but it is driven through the wrong

the pipe A quirk disabled since it makes the boot console unusable
(which might explain something).
