Here is the output from before the problematic patch (ie. when the
screen worked with suspend/resume).

A couple of things:

* It looks like the card is getting powered down twice.
* It looks like the video state is saved after attempting to set the
power state the first time.  So that probably isn't the problem

So the code that saves the card state is failing mysteriously after
274386.  I doubt this is the fault of the ACPI changes that patch made.
 Add to that the fact that the efifb and vga text mode suspends
apparently never worked, and I'd say it's probably something in the card
state save/restore code.

So I guess I'll go poke around in that code for a while and see what I
can find.
