Here you probably need the IGD parts also.

Some machines need a switch to console 1 and back to X.
Don't ask me what is missing and what X could do here
automatically. We have a workaround to just switch the
displays after suspend (not sure whether it's on by default)
but it's a config variable.

It's a Dell..., is the dcdbas driver involved?
See discussion on my previous posts with Matthew and
the Dell hal bug. Could be related..

Sounds worth a test.

No idea. I have a bug where a lot HP people reported a freeze
when using the LID. They should be lucky that only backlight
is dark :).
Oh wait, _DOS=1 works, _DOS=0 fails -> probably the same
issue. This one is nasty and very critical (a lot HPs freeze), but I did
not have time to look at anything.

Defintely worth a test with IGD enhancements.

I just had a quick look on each, do not give much on above statements.
If there is any outcome on 9642 (_DOS=1 works, _DOS=0 fails on HPs and LID),
pls let me know.
