APM Daemon in Mandrake

Fellow GLLUGers,
My brother-in-law is running Mandrake 8.0 and he had his PC over for some
tweaking the other day. At one point, I noticed that the CPU meter was
pegged at around 100%. A quick check showed that the 'kapm-idled' process
was hogging the "lion's share" by far.
Assuming it was some sort of APM daemon, I tried to kill the process, but it
seemed to either keep respawning or just didn't die. I've forgotten, but I
think the PID was unchanging, so I guess maybe it just wouldn't die.
Oddly enough, the CPU usage later (several minutes later, I think) dropped to
normal (i.e. almost 0%) of it's own accord, with no explicable reason! The
'kapm-idled' had relinquished it's death grip, apparently. :^)
Just tonight, I checked a log file output from a script that I had him run
several days ago with lots of good info (like 'ps -aux'). I see from that
log that the 'kapm-idled' process has been really hogging the CPU rather
routinely! Here's a little excerpt (much editted) from the 'ps -aux' output
section:
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 1 0.0 0.0 1356 76 ? S Dec12 0:04 init
root 2 0.0 0.0 0 0 ? SW Dec12 0:00 [keventd]
root 3 25.9 0.0 0 0 ? SW Dec12 4121:14 [kapm-idled]
root 4 0.0 0.0 0 0 ? SW Dec12 0:18 [kswapd]
root 5 0.0 0.0 0 0 ? SW Dec12 0:00 [kreclaimd]
root 11235 0.4 0.9 86660 1160 ? SL Dec16 42:15 /etc/X11/X
Something seems clearly out of whack here. This snapshot comes after just
over 11 days of uptime. Compare 'X' (2nd largest) usage with 'kapm-idled'
usage. On my (Slackware) system, APM is disabled, and 'X' and 'Emacs' (I
'live' in Emacs ;^) ) are the top 2 "heavy time users", but nothing like
'kapm-idled'!!!
Can anybody running Mandrake with APM enabled confirm/deny the fact that the
'kapm-idled' process is hogging CPU?
Does anyone know why this might be happening? I'm befuddled and I don't have
Mandrake to test it out.
TIA....
P.S. Many thanks to Paul Melson for his advice a few months back in getting
the Mandrake GUI login back after it "broke". This has mysteriously happened
more than once on my bro-in-law's PC and Paul's advice was the perfect fix!
