Thanks for the dmidecode.
Looks like we should just match on the string "Apple",
since they seem to have cut over from "Apple Computer, Inc."
to "Apple Inc."

btw. if you can send me the output from acpidump, I'd
like to look it over, since I've not see the MacBookPro3,1
version yet.

thanks,

Thanks for the acpidump.
Apple has added new code BIOS to test OSYS.

But it looks like a NOP for Linux.

I also looks like the Apple BIOS programmers don't
realize that Windows 2006 returns true for OSI(Windows 2001).
But since they test OSYS only against 0x7D1 and the Darwin
value, that bug isn't noticed yet.

cheers,
