A little more information on this: to control the Thinkpad fan
speed, the thinkpad_acpi module must be loaded with the
option fan_control=1. I have a line that arranges that in
/etc/modprobe.d/modprobe.conf. Apparently this is not
respected by kmod. I tried the experiment of

modprobe -r thinkpad_acpi
modprobe thinkpad_acpi

(using module-init-tools, that is) and now thinkfan works again.
So my next question is, how to ensure that kmod picks up on
the option. I guess I ought to be able to find that myself.
