Well I found something that works.

I added an acpi=force kernel parameter. ACPI loaded and shutdown now 
powers off the box.

Yeah!

I spotted the work-around in another thread where it is used to get 
around the ACPI BIOS age cutoff.

Not sure what happen after 2.6.11. I'll try to let the ACPI project know 
this occurred.
