Applied with no rejects to 2.6.15-rc1, and runs OK. I noticed it doesn't
crank up the fan as aggressive as the original driver, resulting in about
2 degrees hotter CPU when I let it run full blast (I set limit_adjust to
-5, that seemed to help a bit with lockups initially. Come to think of it,
that's not really happened all that often, and it's over a year since).
I'll see if reintroducing fan_speed gets me back to the old values.
Other than that, I'd say I'll send it off to BenH.

Uh, that sounds scary. Although your code does ramp up the fan speed a lot
slower than the original code. You might try to crank it up to full speed
once the the limit is exceeded by 10 degrees or so, with no delay.
Speaking of tweaking these parameters: Is there a panel applet to display
temperatures from sysfs anywhere?
