The last time I fooled with this, it appeared as though the -nolisten tcp
option is hard coded in the program that gdm uses to start the X server.
The best idea I've had is to replace the X server with a C program that
fiddles with the option string then exec()s the original X server
(but I haven't actually done it :-).

I ran it under strace and couldn't find anything that looked like a config
file it might be opening or trying to open to get server options.
