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.
