I have a couple of suggestions, which may or may not be off base. I had
some of the same kind of problems when I installed a cd rewriteable
drive in my system. It's not exactly the same problem as you had, but
there are some similarities.

At this spot have you tried setting IDEDISK to y instead of m?

Not being familiar with some of the hardware you had specified
previously I couldn't tell what SCSI equipment you had, or whether you
booted from SCSI or IDE. Obviously, if you don't need SCSI support
disable it.

The suggestion which was given to me was to make ide cdrom support and
scsi cdrom support fully modular and unload one or the other as needed.
Another possibility is using the ide cdrom with the ide-scsi module,
which is the way I finally went.

I hope some of this helps.
