Agreed. Automagicness is great until it breaks and then you wish you
could just fscking mount -t iso9660 /dev/hda /media/cdrom.

That's *probably* different. That may be fixable by linking /dev/cdrom
to the proper device. You can test if it is the same problem as me by
inserting a data disk in the drive and then try mounting it manually
using the correct device (hda, sr0, whatever). If it fails with no
media found, see if it works for a dvd data disk. My issue is that dvd
works, but cdrom's do not.
