Hi,
I am using a not-so-new Tyan Thunder K8W S2885 based Dual Opteron System.

Cannot tell as I am using a 64-bit kernel without HPET. Can someone maybe tell me which applications use HPET yet?

Cannot confirm this, both 2.6.8.1 and 2.6.9 boot OK.

Cannot confirm this, interrupts seem to be almost equally distributed with 64-bit kernel and irqbalance running. Did you note that x86_64 does not provide in-kernel IRQ balancing.

AFAIK power management is almost unsupported on SMP systems.
