ide-scsi multiplies cd-roms for quite some time...

For some months, the kernel thinks I have eight times more CD-ROM's than
in reality, and finally I had a bit of time to even report it... The hw
setup is not really unique, just a single ATAPI cd-rom on a different
channel than a single IDE hard disk. The scsi core is compiled in, but
ide-scsi, cdrom, and sr_mod are loaded as modules.

On module load, I get the following:

...etc, you get the picture..

What could cause this? I looked back in the logs, and it seems it
happened to me first back in January, with 2.1.79. The boot before that
was with 2.1.75, and that did not do this. On another host with
multiple ATAPI devices, this doesn't happen either, not even with recent
kernels.
