I'm not exactly happy with those "one-less-layer" solutions for the
devices that are SCSI in nature (like ide-{cd|tape|floppy} or this one)
but at least they have a smaller memory footprint than a multi-layer
SCSI-based implementation. I hope the "low performace" here means that
the devices are slow, not the driver though... :-)
