As Daniel said, this is not a livecd problem, but an x.org problem. Even if 
livecd did run a hardware detection utility it still would have to be the 
x.org system that acted upon the input. I've run into this from time to time 
when installing a distribution. The only solution is to boot into a text 
console and edit the xorg.conf file.

Agreed, it's not a good solution if you're trying to interest someone in 
Linux, but the solution is not a cludge to livecd, but rather to (a) use a 
display monitor that correctly identifies itself or (b) turn in a bug report 
to x.org to update their display monitor database.
