Sorry, no TSM/debian experience, but I'm in the same position, trying to move from Solaris to Red Hat EL4. The IBMTape-drivers are available from ftp://ftp.software.ibm.com/storage/devdrvr/Linux/, but not for RHEL4 or debian. I have a support request in at IBM asking for IBMTape-drivers for RHEL-4 kernels, or plain 2.6-kernels from kernel.org, but haven't heard back yet.
