I'd like this to be two three-way flags: video_bios_reset and
video_mode_reset. Each can be set to yes, no, or default.

Yes means force to true. No means force to false. Default means default Xen
policy (i.e., false unless changed by Xen command-line option
'acpi_sleep=').

If video_bios_reset is true, we call c000:0003.

If video_mode_reset is true, we reset video mode to what we set up at boot
time.

Anything other wakeup re-set should be done by dom0 itself.
