Sorry, I'm not really much of an ACPI or Mac expert.  I don't see anything
relevant.  IIRC, the vbios on macs is only available in boot services so it's
likely gone by the time the OS is loaded.  You'd probably need the boot loader
to grab it and store a copy somewhere so the OS can access it when it loads. 
I'm not sure how Apple does it.  Someone more familiar with Macs may have some
ideas.
