leave the standard rc scripts in there. Make sure that xdm/gdm/kdm is
not started via symlinks from /etc/rc2.d. Add the respawn in as an extra
runlevel 2 respawn.

Heck, come to think of it, you could make an /etc/init.d/kiosk script
that starts the kiosk, and stick it at the end of the rc2 startup.

The su -c command should change to a acceptable user. Interesting error.
If you change su -c /usr/local/bin/runkiosk kioskuser to su -c
/usr/local/bin/runkiosk root, does it work? (not that thats a solution,
just helps in locating the problem)

Your .Xsession would be just 'galeon -geometry 1024x768+0+0'. No window
manager at all.

If your kernel has ext3 support built in, use tune2fs to convert to
ext3. /boot can be ext3 aswell.
