Lars, are you running that with p4tcc and acpi_throttle both disabled?

That is, what says `sysctl dev.cpu.0.freq_levels`?

On my X200 it's '2401/35000 2400/35000 1600/15000 800/12000' and I found 
hiadaptive rather aggressive, where adaptive works fine for my use - but 
of course everybody's use is different :)

powerd_flags="-a adp -b adp -i 70 -r 90"

cheers, Ian
