Yeehaa..
I wonder how many devices decode all 32 bits of an IO address. Maybe they all do, but it sure hasn't gotten any testing by anybody. Considering that ISA devices even today often only decode 10 bits for historical reasons, I wouldn't find it surprising at all if there are PCI devices that only bother with the low 16 bits - and they'd be really unhappy with any aliasing...
