	Thanks.  That helped.  I've got "shutdown -p now" back now as
	well.  The back light was more important than power management
	so I had disabled acpi between between sessions.

	Standby still has the same symptoms.  I added
	hw.acpi.video.out0.active=1 to sysctl.conf in case it was rebooting
	so it would restore the back light on the way up.  This doesn't
	appear to be the case.

	Mark
