I have such a drive successfully set up. (The Exabyte Eagle TR-4i) I use
the X-windows bru configuration tool, which made life MUCH easier. But
here are some of my entries from /dev/brutab

I've been wondering about the bug you refer to. What I've found, about
keeping multiple archives on one tape, is that the "rewind to previous
archive" command doesn't work. Apparently, rewinding to a tape mark
doesn't work. But seeking *forward* to a tape mark works.
Using xbru (I don't know if bru does the same thing), it automatically
verifies an archive after it is finished. It uses the "rewind to previous
file" (or whatever the appropriate term is) -- or the "bfmcmd" above. When
that fails, xbru rewinds the tape and seeks forward until it finds the
archive, and then does the verify pass. That works.
I have heard (rumors?) that this bug is fixed in the developmental kernels?
But I'll wait for it to trickle back to 2.0.X. Or for 2.2.0 to appear. It
works "good enough" for now. <grin>

P.S. If you have X running, I highly running xbru (for attended backups)
and bruconfig to configure everything.
P.P.S. RPM is truly a wonderful tool:
$ rpm -qa | grep -i bru
BRU2000-15.0P-2
BRU2000-X11-15.0P-2
$ rpm -ql BRU2000-X11-15.0P-2 | grep X11R6
/usr/X11R6/bin/bruconfig
/usr/X11R6/bin/xbru
and viola -- we know what executables this package gives us for X.
