It depends from point of view. Try to run Ubuntu Live CD on computer, which has
less than 192 MB RAM and no swap partition (for example 128 MB) and you see,
that every megabyte is important and maybe because of gdm running in background
users cannot use Ubuntu Live CD on computers, which have 128 Mb RAM :( Other
Live CD's, who doesn't use Ubuntu technology (for example KNOPPIX) starts on
computer with 128 MB RAM and without linux swap partition without problems.

I just looked on gdm memory usage while writing this comment:

baltix-linux:~# ps aux |grep gdm
root      7013  0.0  0.5  11456  2600 ?        Ss   16:08   0:00 /usr/sbin/gdm
root      7014  0.0  0.6  12004  3216 ?        S    16:08   0:00 /usr/sbin/gdm

I didn't exactly tested how removing gdm on startup would increase Live CD
startup time, but I'm sure, that this depends on amount of RAM in computer. If
computer has 192 MB RAM or more, then gdm doesn't increase startup time, but on
systems with 128-160 RAM and without swap partition gdm increases startup time.
