E.g. at 150F it'd go max 1.2GHz, 165 = .8, 180 = .6.

You may have to boot with acpi=off for gkrellm to work. I've been using it to work around a combination kernel/hal problem that affects my Latitude L400. https://bugs.launchpad.net/ubuntu/+source/hal/+bug/127773 https://bugs.launchpad.net/ubuntu/+source/linux-source-2.6.22/+bug/127772 Are the relevants bugs for background on what I had to do.
