yes. x86 (Foster, ie HyperThreading CPU) does too.
80-90% of iosapic.c for ia64 and parisc are functionally identical.
IIRC, differences are in "discovery" and PCI routing table setup.
Haven't looked at x86 version yet.

If someone wants to merge them, I can make HW available remotely.
I've got all the HW but not the time. :^(
(IA64 rx2600 and PARISC A500 are already remotely accessible).
