Yes; that much of it "feels" about right.

Assuredly not, but I understand the rationale behind the question. :-)
(I have the "script" log available for perusal....)

OK; that's a good & useful thing to keep in mind. And I did see some
IRQ-related entries in top's output.

Eh... the "enlightenment" line may provide a clue there. I use tvtwm as
a window manager. :-} (I figure anything that could be marginally
acceptable on a (maxed out) 24 MB Sun 3/60 ought to be adequate for this
750 MHz/256 MB laptop....)
