Cool.

Strange, cant say I've seen this before.

Yeah, we were the first to support these machines and at the time of the
release, we had no thermal support.

The solution is to yum update, and then edit your /etc/yaboot.conf, and
run ybin.

I'd recommend any firewire enclosure... as far as I know, they're all
the same. Unlike in YDL 3.0.1, firewire is fairly easy in 4.0 (we're
actually working on making anaconda install to firewire drives for 4.1).
