I had assumed that v2.01 was the version widely available now - sorry
about that.
pandaboot.zip also contains those naughty MLOs that tempt you into
overclocking land like me...

Exactly as I said.

Interestingly this confirms what others have said before that heavy
use of the network heats things up a bit.
Those temperatures are a little on the high side but will be just
fine.
Once support for SmartReflex comes out for the PandaBoard (it is
already there for the BeagleBoard) you'll see those temperatures drop
quite significantly.

Yikes!
A PandaBoard shuts itself down when it reaches 85 :-D
