by [1.] Cannot mount IDE cdrom if SCSI-emulated
[2.] I cannot use my IDE/ATAPI cd-rw device for any operation, because
emulating the SCSI mode with ide-scsi give me some errors (sometimes "hdc:
driver not present" or "ide-scsi: unsup command: dev 16:00: REQ_CMD
REQ_STARTED sector 0, nr/cnr 1/1"). When I try to mount the device I get
the error "Invalid block device" if using the device /dev/scd0, and "mount:
error while guessing filesystem type" and "error reading superblock" if
using /dev/hdc. Everything works fine without ide-scsi emulation and with
2.4.x kernels.
