6.06LTS problem with Quantum DDS4 DAT Drive

    I've installed 6.06 LTS LAMP server on a machine with an Adaptec 
controller.  The RAID array is on channel 0 and a Quantum DDS4 DAT Drive 
is on channel
1.   I've run the Adaptec setup 'detect' software to make sure that the 
SCSI BIOS recognizes
that the DDS4 drive is attached.

    I went to the Quantum site and followed the directions for Linux 
install including running
'modinfo st' which returns...

parm:           buffer_kbs:Default driver buffer size for fixed block 
mode (KB; 32) (int)

    ... but my dmesg output contains only
st: Version 20050830, fixed bufsize 32768, s/g segs 256
    ... and not the "attached scsi tape device" kind of detail I was 

    The st device files do not show up in /dev and MAKEDEV -v returns...
/dev# MAKEDEV -v st
create st0      c 9 0 root:tape 0660
create nst0     c 9 128 root:tape 0660
create st0l     c 9 32 root:tape 0660
create nst0l    c 9 160 root:tape 0660
create st0m     c 9 64 root:tape 0660
create nst0m    c 9 192 root:tape 0660
create st0a     c 9 96 root:tape 0660
create nst0a    c 9 224 root:tape 0660

    ... so I created the character special files with mknod and then ran 
stinit which returns...

/dev# stinit
Initialized 0 tape devices.

    At this point I'm stuck any suggestions welcome.
