I know nothing about windfarm stuff (I use ancient Mac hardware) but
regarding /proc/cpuinfo -- treat it as if it's a text file:

cat /proc/cpuinfo

this should dump its contents to the terminal.

As for not being able to find the windfarm kernel module, you could
try this command (IF the machine has been running more than a day --
long enough to generate the locate database):

locate windfarm

if you find any .ko files with the word windfarm in them you might get
a clue about why it won't load. (I'm running Breezy and it's NOT
anywhere on my system. You would normally expect a module to be in the
/lib/modules/[kernelversion]/kernel/drivers/ directories) It sounds
like (from earlier comments in the thread) the module only exists in
Dapper. Now I don't recall whether you're running Dapper, but even if
you're not, you may be able to compile just that module for your
kernel version.

P.S.: I know this has nothing to do with linux but you might find it
interesting that even under OS X, on some Macs the fans kick into full
speed when you're operating in single-user mode (not a normal boot).
There's a bug where first generation iMac G5s machines do not resume
operating normally when returning to multi-user mode, as described in
this Apple tech note:
