So I won't be able to use any of the CD burners I have now.
Use the SG_IO interface, it should be the default if you just specify dev=/dev/hdc instead of faking some SCSI like device enumeration for ATAPI.

If you read the above, it was about 2.4 and using ide-cd instead of ide-scsi there. In 2.6 you have two options outside of ide-scsi: one is the CDROM_SEND_PACKET (which is what the dev=ATAPI:1,1,0 above used) which works in both 2.4 and 2.6, but is absolutely crap and not recommended. The other is the SG_IO method, which is the recommended approach.
