This has changed the behavior of the HPET timers somewhat.

With patch5 I was seeing approximately equal interrupt counts from
hpet0 and hpet1.

Now the majority of interrupts are on hpet0 by a factor of 6 to 10.

Not a show stopper, just thought I'd mention it.

One difference is that I didn't apply tm6292_idle.patch this time.
