Actually, this is exactly what my "supermount" patches do (available
for 2.0 on in /pub/linux/supermount!). It provides
truly transparent removable media support for both floppy and cdrom.

There are a couple of problems with the current release. Only msdos
and iso9660 filesystems are supported, and the door locking on 2.0
kernels means that you can't change disks on cdroms for many drives
which were OK on 1.2. The 0.5 releae of supermount is in progress and
under testing, and will address these deficiencies.
