There's one hit now for "ibm-fancontrol.pl" .. your message :)  Without 
the quotes shows some interesting stuff, but nothing FreeBSD-specific.
Such as: http://www.thinkwiki.org/wiki/How_to_control_fan_speed

Or once was?  A mystery.  I don't recall having seen this one before.

It's a lot more heavy duty, starting and stopping powerd and controlling 
CPU freq directly too.  I like the direct mapping of temperatures to fan 
speeds, though my normal operating range at idle is 44-48C, while on 
full fan there's nothing I can run to get my T23 over ~80C in summer, 
~65C winter (ie now :) so I wasn't looking at powerd interaction too.

FWIW, my little script lives at http://smithi.id.au/temp_t23
