Ok, what about the rest of the stuff?

I have now located also a powerd error, (bug?) mainly the frequencies picked 
off by acpi are unavailable - this is a p4 1.6Ghz and it seems uncapable of 
clocking itself down to 1200Mhz.

The levels said to be supported are:

dev.cpu.0.freq: 1600
dev.cpu.0.freq_levels: 1600/22000 1400/19250 1200/9800 1050/8575 1000/13750 
900/7350 800/11000 750/6125 600/8250 450/3675 400/5500 300/2450 200/2750 
150/1225

The ones actually supported are 1400, 1000, 800, 600, 400, 200.

The other ones do not work, whether booting from A/C and then switching to 
battery, or whether starting on A/C or starting on battery.

ttyp1 10:38 # sysctl dev.cpu.0.freq=450
dev.cpu.0.freq: 1600
sysctl: dev.cpu.0.freq: Device not configured

and in messages:

acpi_perf0: Px transition to 1200 failed
acpi_perf0: set freq failed, err 6

Any ideas, good people? :-)

Cheers,
