I think that's muru.com/linux/dyntick ?

I'm not sure what Thomas's patch will do for me - here's what I currently have:

% cat /proc/acpi/processor/CPU0/power
active state: C2
max_cstate: C8
bus master activity: 00000000
states:
C1: type[C1] promotion[C2] demotion[--] latency[000] usage[00000010]
*C2: type[C2] promotion[--] demotion[C1] latency[050] usage[01314979]

Near as I can tell, we start off in C1, drop into C2, and stay there no
matter what happens - we never move back up to C1, and there's no C3 to drop
into....

Should there be a C3/C4? Is my laptop just plain borked? :)
