I've been booting with "acpi=off", but I'd rather have it enabled and
not causing this problem.  The kernel is compiled WITH the ACPI-PM timer
support.  Perhaps I should try building one without that?  HPET is very
new, am I correct?  This laptop does not seem to have one.  Would the
"unsynced tsc support" option (2.4) affect this?  IO-APIC?  I really
need to find out what class I need to take where they'll teach me what
all that stuff means!  It's embarrassing to have been around Linux this
long and not know what that stuff is.  Anyone know a good book where I
can read about it?  {Please.}

First I will try to turn off the battery monitor in the gkrellm that I
always have running.

cpufreq is enabled even without ACPI, and it's working fine; Centrino
enhanced.  That does not seem to be the cause of the problem.
