BTW, my first idea was to use an acpi method that looks up pmbase in
the pci cfg space, but when I define a method like this:
Method(TEST, 2)
{
Return (Add(Arg0, Arg1))
}
I get:
|build/mainboard/asus/p2b/dsdt.ramstage.asl 9: Processor (CPU0,
|0x01, TEST(0xe400, 0x10), 0x06) {}
|Error 4096 - syntax error, unexpected PARSEOP_NAMESEG,

While using the builtin Add() directly works.
