I got no responses from the above, so I took the matter in my own hands 
and created a custom Live-CD, based on 12.04 beta1, with the only 
difference that it boots and installs a non-pae kernel instead of the 
pae one.

It's available here for those who want it:
http://people.canonical.com/~diwic/12.04-nonpae/

Note that this is work made by somebody who is not a LiveCD expert by 
any means, never made a custom LiveCD before, and merely followed the 
instructions here [1]. You have been warned. :-)
