Re-reading your post, I see you are trying to get the live
CD running. Same instructions as above - except don't
reboot. Instead, restart X by ctrl-alt-backspace. The
"reboot" is for fixing HD install.

I have pentium 1 with 96mb and serial mouse running XUbuntu
6.06. Not terribly speedy, but it does work, even the mouse!
