Cheers! This was of course the correct answer; and it does sound
familiar now. Is there some vital bit of documentation I've managed to
skip? My attempts to google for the answer only turned up using ukc to
enable acpi, with no mention of needing to disable apm.
Anyway, the intent was to see about throttling back the CPU of this
machine a little so the fan would slow down and shut. Using apm didn't
work. Enabling acpi doesn't seem to have helped this either.
There's no hw.setperf available, which kinda implies that the CPU
doesn't support throttling, and as there's no obvious way to affect
fan speed I suspect I'm just going to fit a much larger, quieter fan
and put up with the system drawing full power all the time, which
isn't actually a whole lot (~40-50W). Anyone else been able to
throttle C7 processors?
