Any reason you couldn't trade this in and go with a SCSI CDROM?

You can't set the cdrom slave since it has nothing to master it.  :(  If
it's not detected in single mode then it ain't gonna work.

FreeBSD doesn't give a hoot.  You can specify which disk the kernel is on
if it gets confused (spits out "can't mount root") but shouldn't be
necessary in most cases.
