Or is it possible to just use the SCSI drivers with the DVD burner via the "hdX=ide-scsi" append line, but have the CD-ROM use the standard IDE drivers?

First off, please learn to use the return key :)

Now, on to the meat of your question.  If you have separate CD-ROM and
CD-RW drives, you can certainly use normal ide (hdx) interface for the
CD-ROM, and the ide-scsi support for the RW.  That's what I do here, and
here's what I do.

Compile the following things *IN* the kernel, not as modules:

SCSI Emulation Support
SCSI CD-ROM support
SCSI Generic support

Now, assuming your CD-ROM drive is hdb, and your burner is hdd, pass
hdd=ide-scsi to the kernel.  This tells the kernel to not use the ide
cdrom driver for device hdd, but instead let the ide-scsi handle it
instead.  Voila, hdb appears as normal, but your hdd RW drive now
actually becomes scd0, a scsi device, which cdrecrod can talk to no

Hope I didn't confuse you too much.
