Yes, this is a standalone drive.

Yes, I md5'ed the files before the backup and after the restore and
diffed the checksums. The checksums were identical.
I am quite convinced that that configuration I have is fine and that
this is a btape problem.
The drive is now in productive operation (remote!) and I don't want to
mess with the config. I might do some tests once I am on location again.
To my understanding, it would make sense to look into how btape differs
from bacula-sd in handling the drive.
As said before, this configuration has worked just fine for LTO1 drives
on FreeBSD with and without an autoloader. I am guessing that the
SCSI/IOCTL interface hasn't changed between the LTO generations.
Thank you for your input, Dan!

Georg
