Since this is quite old with no change for quite some time, and since
there is also a newer discussion at
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/262550, I am
marking this as a duplicate. Hope
Intrepid and 2.6.27 solved this problem for me. I think you can close it
now.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the
upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would
appreciate it if you could please test this newer 2.6.27 Ubuntu kernel.
There are one of two ways you should be able to test:
1) If you are comfortable
This is still an issue for me under hardy. I have an MacBook1,1.
Tried intrepid yesterday and it seems to get better, need to test it longer
though.

I notice the same behavior with the standard kernel from feisty and a gutsy
2.6.22 kernel from git with mactel patches applied. I have a Macbook Pro with a
C2D processor.
The acpi-cpufreq module seems to work. It sets the correct values for the MSRs
and a lower frequency is displayed. But if
I have a fully updated Edgy system and it gets very hot when running
idle and I get about 1/2 the battery life of what I can expect in OS X.
I found this and tried it:
http://wiki.debian.org/MacBook
CPU frequency scaling is governed by SPEEDSTEP_CENTRINO kernel module.
echo speedstep_centrino
Can someone test this with Edgy + updates and Feisty so we can see if
this bug can be closed?

In reference to my comment above, it holds the speed during a reboot
from OSX to Ubuntu (using refit). It's a step in the right direction, I
suppose.

This may be a fix.
A new GPL'ed OSX application called smcFanControl allows a user to
control the minimum fan speed on Intel MacBooks through a simple
interface. It appears that this minimum fan speed setting carries over
into Edgy without issue on a multi-boot system, but more testing is
needed.
This is not fixed in current Edgy. There is no temperature information
in /proc and the MacBook slowly gets hotter even when almost idle.
With coretemp.c [1] I can see the temperature of the two cores going up
to about 78 and 79 degrees Celcius and at that point the fan kicks in.
The fan seems to

I have a Macbook Ultimate (as the Apple retail stores call it) and I
haven't had any issues with the heat under Ubuntu Edgy. Could any of
you try a Edgy Beta and see if the problems persist.

I also noticed my MacBook (Black) getting very hot (much hotter than in
OS X). I recently applied a firmware update which claimed to improve fan
behavior, but so far I didn't notice any difference.
The directories /proc/acpi/fan/ and /proc/acpi/thermal_zone/ are both
empty - so Ubuntu's power

Same problem here.
I notice that acpi -V says: No support for device type: thermal.
Gnome CPU-Frequency-applet shows 54% (1.0GHz out of 1.83GHz max) for both cores
when idling.
Under similar conditions the OS X frequency is usually 1.5GHz. Yet,
after running Ubuntu for a while the area around
When I saved (submitted) the above message, one of the core
frequencies shot momentarily up to 100%, only to quickly settle down to
54% again in a number of steps. So, I don't think that the problem is
CPU frequency related...
One difference that I notice is that without input activity the screen
I have the same problem.
