Ouch.  That sounds familiar from early days of debugging the install.
It sounds like your Frankenmachine is a 586, and needs the restricted
kernel I put in build 161.  The next major release should probably
include a 586 version as well...

Good News and Bad News:
The good news is that nothing on the laptop cares whether it is using  
a regular AP or a mesh to connect to a school server.
The bad news is that backup is still being implemented...  It is on  
the high priority list for the next release of laptop software
(8.2, due out in August).   We have scripts that you can try with a  
school server now, for disaster recovery purposes.
