Similar to the local APIC changes, the IO-APIC access mechanisms should also be 
restricted to the Xen-specific ones
(other than for the local APIC, where the access mechanisms must be entirely 
suppressed). A nice side effect of this is
that the fixmap area shrinks quite a bit, allowing 32-bits to use a little more 
low memory.
