17" Powerbook fan turns on when starting into Ubuntu Dapper

[Adam D]

OK,  I decided to just install Ubuntu on the 2nd Gen 17" powerbook with ext3 as the file system and it works for now instead of booting into xfs.  

Upon startup and starting the network interfaces and then the portmap the fan turns on full throttle and spins for a while. It is semi loud and is rather annoying.   Is there a way not to have the fan spin when booting into Ubunto on startup?
