I did a server install with Ubuntu 7.10 (i386) server edition a few days ago and the user thomas created in the install process is in the following groups:
# grep thomas /etc/group adm:x:4:thomas dialout:x:20:thomas cdrom:x:24:thomas floppy:x:25:thomas audio:x:29:thomas dip:x:30:thomas video:x:44:thomas plugdev:x:46:thomas scanner:x:104:thomas thomas:x:1000: lpadmin:x:109:thomas admin:x:110:thomas
So for me it worked fine.
