A while ago I asked for help with the above configuration which would hang
during boot. 

Well, it turns out that the aha1540 driver in Ix/386 2.2 times out the
scsi inquiry function a bit to fast for the slow DAT tape. I've fixed
that for now with a patch to the aha1540 driver in ix2.2. The tape
runs ok while a little bit slow - I just get about 100KB/s instead of the
180KB/s advertised with the HP35450A.

If anybody's interested in the patch, send me mail.

PS: Dear Interactive-People: What about making the timeout parameter
    configurable in aha1540/space.c ?
