It is in C0 less than 1% of the time. Here's a snapshot of the powertop
output:
OpenSolaris PowerTOP version 1.2
C-states (idle power) Avg Residency P-states (frequencies)
C0 (cpu running) (0.9%) 800 Mhz 0.0%
C1 4.0ms (99.1%) 1060 Mhz 0.0%
1330 Mhz 100.0%
Wakeups-from-idle per second: 491.8 interval: 5.0s
Power usage (ACPI estimate): 0.000W (running on AC power, fully charged)
Top causes for wakeups:
20.3% (100.0) <kernel> : genunix`clock
16.0% ( 78.8) <kernel> : genunix`cv_wakeup
9.5% ( 46.9) sched : <xcalls> unix`dtrace_xcall_func
5.0% ( 24.7) <interrupt> : iwk#0
3.1% ( 15.4) <kernel> : uhci`uhci_handle_root_hub_status_change
2.0% ( 10.0) <kernel> : genunix`delay_wakeup
1.1% ( 5.2) <interrupt> : e1000g#0
0.8% ( 4.0) <kernel> : genunix`schedpaging
0.8% ( 4.0) <kernel> : uhci`uhci_cmd_timeout_hdlr
