Woohoo!  This latter one works for me on a Dell 640m using the Intel
i945 graphics.  This is with machdep.acpi_vbios_reset=0.

Previously the only way I've been able to get a working display after
suspend is to attempt to start X.  X actually fails to start, but does
re-enable the display in the process.

Cheers,
