Well, I wrote the thing, so maybe I can help!

Did you ever have any sensors detected using an earlier kernel?  Which 
one(s)?  Do you have a dmesg from both the older and current kernel so 
we can compare?

I don't have any macppc hardware to play with, so I converted the 
'dbcool at ki2c' blindly.  I expected it to work, but you never know!

Also, I would expect the fans to run at full speed until you've used the 
various sysctl(8) variables to tune the PWM algorithm.  See 'sysctl 
hw.dbcool' and 'man 4 dbcool' for description of the sysctl stuff.
