After booting into 2.6 with hdd=ide-scsi, then trying to rmmod ide-scsi,
I get the following Oops:

The kernel and latest modutils are installed from
people.redhat.com/arjanv/2.5, otherwise the system is RH9 on dual athlons.
So, is this just a user and/or userspace error? The system seems stable
enough afterwards, but will not shutdown cleanly.

I submitted a patch to linux-scsi for this Friday. Look here:
