Here is what I did and it seems to have solved the problem:
I just created my own permissions file for udev in /etc/udev/permissions.d:
#> ls -l
total 4
-rw-r--r--  1 root root  163 Dec 15 21:26 00hs-udev.permissions
-rw-r--r--  1 root root 2674 Oct 30 06:56 udev.permissions

#> cat 00hs-udev.permissions
#permissions added by HS,15Dec,2004, based on:
#  http://wiki2.archlinux.org/index.php/UdevHowTo

#to make CDROMs root:cdrom
hdc:root:cdrom:660
hdd:root:cdrom:660


So, after restarting udev:
#> /etc/init.d/udev restart
Recreating device nodes...done.

I got /dev/hd[cd] as root:cdrom.  BTW, for the CDROM reader, hdc, 440 
will also do, right? I cannot write to it anyway.



Regarding adding myself (or any other user) to the 'disk' groups, isn't 
that a bad idea? I hit upon this option when I first installed Sarge and 
people  here told me *never* to add normal users to the 'disk' group.
