OK. So the answer seems to be to stay out of X most of the time. That's
fine by me. But I'm still puzzled by the change in behaviour after
upgrading the kernel (that's the only thing I changed) ... Is there any
powerpc equivalent of the "Do APM Idle calls when idle" option on x86,
that would just have been disabled in the benh tree ? 

(Or could it simply be that the heat output was just below critical and
then the room temperature went up by half a degree ... No, I think the
laptop is perceivably hotter than it used to be.)

Thanks anyway,
