In a related incident... :-)

I set up a 128Mb optical catrtidge with mkfs, etc., and was unable to
get it recognized as a filesystem under MacBSD (I boot from another
drive).  I am using an Epson optical drive (MO5010 I think, I'm not at
home right now), and during the boot process it tells me that the
device is not claimed by a driver, or something like that.  It would be
really nice to keep /usr/src on a cartridge...

Is there anything I can do to help get support for this device added?
I have worked with SCSI devices before, adding support for new tape
drives to a Mac backup program.  I have yet to do a successful kernel
build, though.  I'm sort of waiting to get the sources for the
GENERIC.48 kernel before I try again.  What's the status on the latest
release, anyway?
