We got so fed-up with vold (not KDE's integration with it) crashing
workstations and the like, that we opted to create a system which worked
a little more like Linux - allowing user mountable devices. We created a
couple of SUID perl scripts call 'mount' and 'umount' which checks a
file in /etc to see if users are allowed to mount a specific device...

(in /etc/usrfstab)
#
# User mountable disks
#
#device         mount           FS      mount
#to mount       point           type    options
/dev/sr0        /cdrom/cdrom0   hsfs    ro,nosuid
/dev/sr1        /cdrom/cdrom1   hsfs    ro,nosuid
/dev/fd0        /floppy/floppy0 pcfs    foldcase

...if they are, then it runs mount/umount as root to do this for you. It
seem to work quite well, but I'm not a security expert. Scripts are
attached. Of course root needs to be aware of them as they override the
normal mount process and are unable to mount anything that is not in
usrfstab.

Since this look fairly like the Linux solution, it integrates fine into
KDE as long as you make sure HAVE_VOLMGT is not defined in config.h
