You could try hacking around in /etc/sysconfig/hwconf ? Obviously make
a backup copy first. :)

Have a look at the output from...

# grep -r snd /etc/*

See if that helps you track down where it's being started from.

Is sndconfig enabled in the various /etc/rc.N directories?

# chkconfig --list | grep -i snd

Have you also tried setting the runlevel to 3 and running startx
manually to see if the problem still occurs there?
