There was a previous attempt to do an hpet emulation. It was in the patches that were used to make Mac OS X run under Qemu. File attached

-----------
Add HPET emulation to qemu (Beth Kon)

This patch adds HPET emulation. It can be disabled with -disable- hpet. An hpet provides a more finely granular clocksource than otherwise available on PC. This means that latency-dependent applications (e.g. multimedia) will generally
be smoother when using the HPET.
