The following patch should fix this.

Subject: ide-scsi in 2.1.132

I can't seem to get ide-scsi to work at all in 2.1.132. It works fine in
2.0.36.
I have an IDE CD-ReWriter on hdc and a (dodgy) IDE CDROM on hdd. Under
2.0.36, with hdc=ide-scsi at the lilo prompt, the rewriter works as a SCSI
device and the CDROM as an IDE device. This is what I want.
Under 2.1.132, with hdc=ide-scsi, both drives work fine as IDE CDROMs, but
the rewriter does not appear as a SCSI device and so I can't write CDs.
Any help would be appreciated.
