Scsi-emulation

I have currently the following hardware:

* IDE CD-R (Mitsumi 2801-TE)
* IDE CD-ROM (Teac 16x, IIRC)

The problem is, that I can't use both at the same time. I have to tell the
kernel that "hdd=cdrom" (the teac drive), and it says that hdd = ATAPI cdrom
(?). The scsi emulation doesn't seem to honour this, and it sees only the
CD-R that gets detected normally. If I move the CD-ROM to be hdb, it gets
detected, but that's unacceptable (UDMA hard drive becomes slow!).

It wouldn't be that bad if I could mount the CD-R through scsi emulation,
but that doesn't seem to work.. But still I should be able to use the IDE
driver for the CD-ROM and the scsi-emu driver for the CD-R!

Has anyone coded a general solution for this? If not, I'll have to kluge
around it.. Or maybe make a general solution, if I can :) I don't care if I
have to use a development kernel as long as this works.

Any pointers to more documentation about scsi emulation would be
appreciated, only docs I've found are the kernel compile-time helps. Yes, I
did search the HOWTOs and the web, but found nothing. (Documentation/
directory doesn't have anything either, not in 2.0.x or 2.1.x)
