Just curious what is/isn't current working in the latest kernels that
Ben has made available?

I've installed Debian on my Pismo yesterday, and the kernel provided by the
potato boot-floppies (2.2.15pre20, don't know if it's from Ben) has been
working fine so far, only thing is sound doesn't work for me (I should be able
to hear something after tuning up volume with gmix, right?).

In particular, is power management working?? (I can't seem to get APM going,
and it is sure draining power...)

I also wondered, my machine was getting very warm, almost hot. But then it
didn't even kick on the fan...

Isn't it supposed to have no fan ?

No it's definitely supposed to have a fan.  It comes on in MacOS.
The problem is that the PMU is not fully supported yet, so it doesn't
understand that the processor is too hot.  I'm trying to find
information about it, but I'm not having much luck.  If anything, try
running Paul's pmud (you can get it from rpmfind.net).  It helps a
little.

Does this mean that I can damage the machine if I just run a high-load

I strongly doubt that. The PMU should handle this autonomously, regardless
of Linux support for the PMU.

There won't be any damage to the machine.  The problem is that when the
processor reaches a certain temperature (one that is above limits) it puts
out a halt instruction.  This causes the machine to lock up.  The
protection against overheating is built into the processor (last time I
checked).  What should happen is that the OS should realize that the
processor is getting too warm, and turn on the fan before that limit is
reached.  Unfortunately, the temperature sensing code doesn't work so
well (or maybe something else), and the fan never comes on.

Don't worry about the machine, somewhere I heard the plastic case can
handle around 250 degrees F, so it's not in any danger of melting.
