I haven't looked closely but I've noticed that these fixes are accessing rq->bio
directly which is a layering violation. Could you de-bio and submit them?
[ AFAIR they are already splitted out in RHEL4 ]

Speaking about ide-scsi, it will be undeprecated after I fix the locking.
Rationale is that ide-scsi is _much_ simpler than ide-{cd,tape}.
[ although it doesn't support all the hardware that ide-{cd,tape} do ]
