Just browsing a few threads after 3 weeks off the net entirely :)
All that power_profile message is letting you know is the initial state
set on boot of the two sysctls power_profile modifies whenever switching
to AC power or to battery: hw.acpi.cpu.cx_lowest and dev.cpu.0.freq
With default values the performance profile sets maximum CPU frequency
and lowest C state C1 on boot, if AC power is detected. In your case
it's probably redundant, but not everything boots at maximum speed.
So it's harmless, at worst.
With your hw.acpi values, the system could be forgiven for thinking this
box could be a laptop (suspend state S3 being apparently available)
Sorry, no help for the wireless, if it's running at full speed.
cheers, Ian
