>Description:
On FreeBSD 7.2-RELEASE I (and powerd) was able to use these levels for CPU frequency:

  % sysctl dev.cpu.0.freq_levels
  dev.cpu.0.freq_levels: 2001/32000 2000/31000 1750/27125
  1600/22000 1400/19250 1200/13000 1050/11375 900/9750
  800/10000 700/8750 600/7500 500/6250 400/5000 300/3750

Now on 8.0-RC1 I am able to use only these:

  % sysctl dev.cpu.0.freq_levels
  dev.cpu.0.freq_levels: 2000/31000 1600/22000 1200/13000

This is not a bug ... having this line in /boot/loader.conf 

hint.acpi_throttle.0.disabled=1 

makes such behavior, please close bug and sorry for useless submit.
