Just one word from someone who have tested and am using both TS3100 &
TS3200s with LTO4 drives; STAY AWAY from lin-tape. It is very kernel
specific and even when you think everything is working fine, it will
come back and bite you later.

I do not use Debian but in RedHat 4 and 5, all I have to do is make
sure "mt-st" and "mtx" packages are installed.

Following is the comparison of with and without lin-tape devices under /dev.

Example WITH lin-tape:           # mt -f /dev/IBMtape0 status
Example WITHOUT lin-tape:    #  mt -f /dev/st0 status

HTH,
Win
