Ok, so it's similar to the local APIC in that respect (and presumably IO 
APIC too, I haven't checked).

But that still just implies that the BAR probably means something else 
totally, and the fact that it happens to have the same value as the MCFG 
is just random luck.

Yeah, I'm not finding anything either. The 690G databook that Rafael 
pointed to does mention the config registers in passing, but it's really 
just about electricals (pin setup etc). No BIOS writers guide indeed..
