No, try giving domain0 genapic a go.
I suspect it will be an issue with x86_64 smp as well. The apic stuff
is on the plate for cleanup for merge as well. Could use some insight
re: xen's apic handling.
To a first approximation: Xen owns the local APICs, but domain0 owns
the I/O APICs. All IOAPIC writes go via Xen which can rewrite them if
necessary (at the moment that's limited to changing the local-apic
target).
