Ah, get the kernel incoming/vmunix-tape.tar.gz and the incoming/README.vmunix-tape file.
This kernel has, and the next released one will also, a patachable
variable called pretend_tobe_mt or something like that. 
You can select what tape drive you want you tape to act like. 
Try and see if it will behave like a 8mm DAT drive. 
Complete details are in the README files.

If it works I can patch the new st.c that is on sun-lamp for
you or you can do it youself! Patches to the 744 st.c will
definately not work, as Michael Hitch went to a data driven tables.
