Yeah, I don't know what's up with that. Machine's running fine,

I knew they were doing something smarter with their proto-USB protocol.
Funny, I didn't know Apple hardware had a 15-IRQ limit. I suppose there
had to be *some* limit.

Meaningful = won't result in the machine shutting down unexpectedly,
i.e. while the keyboard or mouse is being used.
Unfortunately, sleepd doesn't do anything remotely like watching
/dev/input .
It turns out that X will do the event watching for me, and put my
machine to sleep after some inactivity. But I won't get that behaviour
from the console. Oh, well.
