Regarding the issue of 2.6 kernel not allowing non-root users to burn
CDs. I used sudo:

<username>   localhost = NOPASSWD: /usr/bin/cdrecord
<username>   localhost = NOPASSWD: /usr/bin/cdrecord.mmap

and then modified /usr/bin/cdrecord:

VERS=`uname -r`
case "$VERS" in
    exec cdrecord.shm "$@"
    exec sudo cdrecord.mmap "$@"

Now I can burn from Gnome's Nautilus as a non-root user again.
