I agree, it's very weird that it should have this effect if the apmd isn't
really doing much on PowerPC.

So, I did the reverse of what I did before (chmod +x /etc/init.d/apmd), and
rebooted, and waited for it to fail again.

However, I couldn't get it to happen. I waited, tried using the mouse, not using
the mouse, waited some more, but simply could not get it go wrong.

This is very annoying, and I can't explain it. Basically last week I simply
could not get it to work, and this week I simply cannot get it to fail. The main
change I remember is changing whether apmd loads or not, and that seemed to make
such an immediate difference that I assumed (incorrectly I now suspect) that it
was the culprit.

The only other thing I can think of is that I installed some USB extensions in
MacOS around the time it started working, and to boot Linux this system has to
first use a MacOS bootloader (called BootX, conceptually similar to the Loadlin
bootloader for DOS). _Maybe_ those extensions are now initializing the USB
subsystem somehow to prevent this problem, but that's really just a guess.

Whether it's this or not, the fact is I can no longer reproduce the problem, and
furthermore even if it is an apmd problem then it's going to be removed in
future Ubuntu versions anyway for this platform.

I think that the best thing is to close this bug (I'll mark it as "WORKSFORME"),
and if I or anyone else runs into this again, and can provide more details, then
they can reopen it and add those details here.

Thank you for your patience and help!

All the best,
Nick.
