I had the same problem with mi little sisters Dell Latitude C600...
There's no floppy drive either, but it's possible to add a floppy drive instead of the cd drive...
I was using the ubuntu 7.04 official release...
But when I waited a few minutes it started to move pass the error and continued the livecd... But I can tell you if the rest of the livecd works :) it doesn't seem have enough ram to run Ubuntu from livecd, perhaps I'll try with Xubuntu...
