FWIW, I have noticed the same behaviour on a Tibook rev III
(PowerBook3,4), though the change in fan behaviour happened to me
between two 2.6 versions (not very sure which ones, but I am almost
sure that 2.6.7 was between the last kernels that made the fan shut up
from time to time).
By the way, I since upgraded the logic board and the machine has
become a rev IV. The fans (now two of them) seem to be on all the
time. This is not so much of a problem anymore since the fans are
much more silent than the original (sole) fan, but I am not sure
whether this is as it should be.
As far as I know the fans are hardware controlled on these models, so
the fans should not be affected by a kernel change... except that they
do just that. Must be grmelins in there or something.
