What is the problem? Is there infrastructure missing in the
CD-ROM layer?

As the CD/DVD/BD part just accepts SCSI/ATAPI commands (except for plain
read/write), I was suggested to keep it as a SCSI driver.

Ok, so I guess the tradeoff here is that by writing it as a SCSI
driver, you don't need to implement any of the cdrom_device_ops
yourself but instead need to fake a few of the SCSI commands
in ps3rom_request(). Fair enough.

ps3rom is just a normal scsi low level driver.  Currently the only
attached devices or MMC devices so the sr driver attaches to it,
but if you want to hack the ps3 hardware you should be able to
attach a tape or disk aswell, and linux would work (lv1 and gameos
might of course not like this)
