Do a `ls -l /dev/cdrom` and I'm guessing you'll see the problem.
/dev/cdrom is usually a symlink to the actual cdrom drive /dev/hdX.
If you add a new drive, the appropriate partition changes, so the 
symlink needs to be changed. `rm cdrom; ln -sv hdX cdrom` should do 
the trick.  (X should be b c or d, depending where the cdrom finally
ended up. b=primary slave, c=secondary master, d=secondary slave.)

BTW, is there any way to access CD changers by disk slot?  I'm thinking 
symlinks of cdrom{A,B,C,D,E}.  IDE Disk changers show up as only one
hdX,
so getting linux to switch CD's is a pain.  (Right now I'm using
`shuffle X-X`.)

It would be great to get my Nakamichi set up with autofs to be able to 
access all my CD's transparently.  Right now, it just accesses whatever
one
happens to have been last chosen.
