I did.  The fan controlling interface changes are in
2.6.32.1-libre-lemote and 2.6.31.8-libre2-lemote (I noticed you
backported them to the 2.6.31-stable branch too).

Unfortunately, they don't seem to help.

sensors reports the temperature steadily rising and the fan stuck at
some 440 RPM, unlike the other laptop in which the fan gets up to some
4800 RPM.

Furthermore, pwmconfig (that's supposed to create /etc/fancontrol) says
there aren't any pwm interfaces.

Regardless, taking over manual control of hwmon1/pwm1 and setting it to
3, as you suggested, didn't change the fan speed at all.  It seems that
439 RPM is its max speed ATM :-(

Unless you have other suggestions, it seems like the only way for this
machine to work reliably (at least until we can fix its fan) is to set
the CPU speed to the minimum.


BTW, is there any hope for auto-detecting machtype in the kernel, rather
than having it passed in from the boot command line?  I'm wondering if
the need for specifying it is a temporary stop-gap or something
long-term that userland must be adjusted for.  Auto-detection would be
highly desirable, but I don't know enough about this hardware to even
begin to tell whether there are any hard impediments to implementing it.
