Ok, I've tried kloading vesa with and without hw.acpi.reset_video and
both cases make matters worse, I never see the disk activity that
suggests that the system is limping along, and the power button
doesn't try to do a shutdown.

I don't have a serial console, would it be worth trying to set up a
firewire console and see if I can get anything out of it.

Is the stuff on the dconschat man page accurate enough that I can use
it as a cookbook?

If I were to go reading through the linux sources and comparing their
thoughts w/ the freebsd thoughts, can anyone suggest places to start?
Is it likely to be under the acpi code, or the console code, or ???
