It's a real IOAPIC all right.  The mobo is a GA-K8VM800M (VIA chipset for 
socket 754).  I suspect Gigabyte misinterpreted the IOAPIC specs, since they 
say the correct value is 11h which they may have though was in binary.

The first few lines of the Linux bootup (just for interests sake) is as 
follows.  Note that the LAPIC address here is different that the one you 
detected.
