This seems to confuse a lot of people.  The SCSI driver does not spit
out messages for devices until they are accessed.  Since the boot
process does not need the tape drive, it is not mentioned.  Try cat-ing
to or from the raw device and you should see an attach message from the
driver.  I currently have the same tape drive hooked to my system and it
works fine.  Note that there are several patches to the SCSI driver for
tape handling.  I don't know if these are included in Terry's 20 patches
or not.

Another "gotcha" (in the FAQ and Buglist, I believe) is that the device
nodes in /dev for ras4* have the wrong major device number and therefore
do not work.  They need to be remade, (especially if your tape drive is
at SCSI address 4.)  From the buglist:

	# cd /dev
	# rm /dev/ras4*
	# mknod ras4a c 13 32
	# mknod ras4d c 13 35
