i'll ask before filling a bug, has anyone seen powertop return something like
na...@saturn:~$ pfexec powertop
OpenSolaris PowerTOP version 1.1   (C) 2008 Intel Corporation

powertop: ../cpufreq.c : cpu-change-speed probe unavailable
Collecting data for 5.00 second(s)

After that all i see is
                        OpenSolaris PowerTOP version 1.1

Cn                      Avg     residency       P-states (frequencies)
C0 (cpu running)                (32.4%) 1000 Mhz        -NaN%
C1                      0.6ms   (67.6%)         1333 Mhz        -NaN%
                                                1833 Mhz        -NaN%

Wakeups-from-idle per second: 1109.7    interval: 5.2s
Power usage (ACPI estimate): 0.001W (running on AC power, fully charged)

Top causes for wakeups:
20.0% (222.1)               <kernel> :  genunix`cv_wakeup
 9.6% (106.7)            <interrupt> :  i8042#0
 9.0% (100.0)               <kernel> :  genunix`clock
 5.3% ( 58.9)                  sched :  <cross calls>
 2.3% ( 25.7)            <interrupt> :  wpi#0
 1.4% ( 15.2)               <kernel> :  uhci`uhci_handle_root_hub_status_change
 0.9% ( 10.1)               <kernel> :  ata`ghd_timeout
 0.9% ( 10.1)               <kernel> :  genunix`delay_wakeup
 0.9% ( 10.1)               <kernel> :  bfe`gem_mii_link_watcher

which is not really informative
It was working properly till i decided it was time to update some
drivers which included  the bios and the dvd drive firmware
