powertop displays the P-states reported by the SBIOS
without any special command line flags. From an i7 920 system:
OpenSolaris PowerTOP version 1.1
C-states (idle power states) Avg residency P-states (frequencies)
C0 (cpu running) (11.4%) 1596 Mhz 0.0%
C1 0.4ms (88.6%) 1729 Mhz 0.0%
1862 Mhz 0.0%
1995 Mhz 0.0%
2128 Mhz 0.0%
2261 Mhz 0.0%
2394 Mhz 0.0%
2527 Mhz 0.0%
2660 Mhz 0.0%
2807 Mhz(turbo) 100.0%
