I have Yonah hardware and would be glad to run tests.

For what it's worth, the perfmon2 Yonah support (at least on the laptop I
have) stopped working after 2.6.23. It looked like a problem with
interrupts not being delivered properly. I never had time to track down
if it was a perfmon2 issue or a generic kernel issue. It was still broken
as of 2.6.29
