I'm not so sure it's an Adaptec controller if it's reporting itself as an
Initio, but I suppose I could be wrong.

Chances are it's the initio.ko module.

Yeah, you're pretty well on the right track. Try running
modprobe initio
as root. Then run dmesg to see if it reports success. Should see something
similar to:
SCSI subsystem driver Revision: 1.00
scsi0 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel A, SCSI Id=7, 32/253 SCBs
scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36
<Adaptec 3960D Ultra160 SCSI adapter>
aic7899: Ultra160 Wide Channel B, SCSI Id=7, 32/253 SCBs
if it is successful.
At that point, make your changes to modprobe.conf and you should be fine for
reboots. The OS should create the /dev/*st0 files for you. In dmesg you
should see something like:
st: Version 20040102, bufsize 32768, max init. bufs 4, s/g segs 16
Attached scsi tape st0 at scsi0, channel 0, id 6, lun 0

Thanks for noting, I CC'd you directly.
