I also can only do it as root from the command line, but if you put it in /etc/fstab, you will be able to mount it normally in Konqueror. In Konqueror, go to devices, then you will see something like cdrom (scd0). Click it and it should mount your cd. This way you dont have to use the command line.

My lines in /etc/fstab related to the cdroms are:
/dev/scd0 /cdrom iso9660 user,unhide,defaults,ro,noexec,noauto 0 0
/dev/scd1 /cdrom1 iso9660 user,unhide,defaults,ro,noexec,noauto 0 0

Keep in mind that you must reboot after changing the fstab file!

Hope this helps!
