64bit with 32bit clients

[Jordan Erickson]

Tom/Asmo, please note that to get your full 8GB RAM in an i386 
installation, you need to install the server kernel on the LTSP server 
(which enables PAE by default and gets past the 3GB RAM limitation).

'sudo apt-get install linux-image-server'


Cheers,
Jordan/Lns
