Yeah, that was the first thing I did... BIOS is newest available.

Yeah.  To me it seems to imply that support for the 0x2D opcode is 
missing from FreeBSD... when I recompile the aml (I get a _WAK returns 
no value warning) and use that, the error is still the same.  To me, 
that implies that the compiler supports it, but the AML interpreter 
doesn't (of course, I know zip about AML, ASL, and ACPI, so my opinion 
is worthless.)
