I think you are going down the wrong path here.

no, but it could be a troll with a snipped dmesg.
Some (at least) PIII-based IBM ThinkPads come up with really funny
processor speeds. Don't sweat it, it has nothing to do with reality
(which is a bummer, 90% of the time, I wish it DID run at <200MHz for
battery life it; is only when I do something with a Mozilla product
that I wish it ran at full speed...plus an extra zero...)
I have a T2? laptop (t22? t23? too lazy to go look, and your snipped
dmesg doesn't give me enough to figure out if yours is the same as
mine (and yes, it says something about my social life that I'd probably
recognize the dmesg more than the model number)). My A21 systems run
fine on APM, but the T2? NEEDS to have APM disabled to use ACPI
instead, otherwise the thing runs WAY too hot.
IF you are having the same problem, I can easily see it locking up
WHEN it got too warm. So instead of trying to force APM, try forcing
ACPI, see if it runs better. You certainly don't want to be shutting
down power management completely, you need it to be working, and on
that thing, you seem to need it working perfectly.
Watching my T22 or T23 (whatever it is) running on ACPI was amazing --
the hw sensors were rather comprehensive, and you could watch the temp
drop as you could feel the thing cooling off...it was obviously MUCH
happier.
