Oh ok.  I'm guessing that's why the FreeBSD code I swiped this stuff from
has "hw.acpi.reset_video".   My laptop's LCD wouldn't come up unless
I reset it, and I left the sysctl out.

I've gotten this code to the point where I can reliably suspend when X11
is running, and the box comes up, and X11 is still running without issues.

Unfortunately I still need to fix pccbb and auich.  (Also see the traffic on
port-i386 regarding the driver/powerhooks stuff.)
