Well,
Given that the tape drive is attached to the Adaptec 2940U SCSI controller, doesn't st have to eventually send SCSI commands to the aic7xxx driver????
Here are the relevent modules after I:
depmod -ae modprobe st
[root@kjc386 root]# lsmod st 29964 0 (unused) ide-scsi 11120 0 sd_mod 13004 2 sr_mod 16888 0 (autoclean) cdrom 31040 0 [sr_mod ide-cd] aic7xxx 130996 1 scsi_mod 102968 6 [st sg sr_mod ide-scsi aic7xxx sd_mod]
But, there is still no mention of the tape drive in /proc/scsi/scsi, nor when I:
cdrecord --scanbus

Is this also reflected on the bios output during post on the scsci controller? Sorry if you already mentioned in a previous, but errantly deleted them.
No, during POST, I can see both devices as id 3 (tape drive) and id 6 (disk drive) before linux boots. I can see both devices using the Auto-SCSI in the SCSI BIOS if I invoke it (it even tells me that the tape drive is not a disk drive!)....
