Got it working with hrt10. However with and without HPET enabled (as I forgot
to actually enable the stupid thing when I went up to .22.rc4 trying to echo
0 to the nmi_watchdog I get a crash in the shell (or in this case, powertop)
On the bright side, the HPET actually saved over 1W and 100 interrupts/second!
Or maybe that was the radeon interrupt going, thinking about it.
