Subject[PATCH] Selective attach for ide-scsi
Today, if you boot 2.6.x with hdd=ide-scsi, ide-scsi will attach to
all your Atapi drives, not just hdd, unless you explicitely specified
another driver for those.

Given that we don't want people to use ide-scsi for cdroms and cd-writers,
that behavior is IMHO suboptimal.

The patch below makes ide-scsi attach ONLY to those drives that you tell
it to. So if you want it to handle hdb and hdd, but not hdc, you boot
with hdb=ide-scsi hdd=ide-scsi.

Regards, Willem Riede.
