I did. RIPLinux-9.3-non-X.iso as emulated IDE CD-ROM boots with
64 bit kernel. An additionally emulated SCSI CD-ROM
  -drive file=/dvdbuffer/netinst.iso,if=scsi,bus=4,unit=0,media=cdrom
appears as /dev/sr0 and is readable.
The emulated IDE CD-ROM appears as /dev/hdc.

Matches the observations.
(I would rather have expected no CD-ROM drive instead of no media.)

Actually i hoped to learn from a working sr.c.
It has similar needs as libburn and could probably do most of the
job of transporting SCSI commands.

Well, ok, there is still ide-cd.c working. So i can at least test the
ATAPI twig of the new function. (As soon as there is something to test.)

Have a nice day :)
