Anyone know when the backup agent for NetWare 6.5 will be available?

I have BE for Windows Servers v 9.1 Rev 4691, which is backing up a couple
NetWare 6.5 boxes. The NetWare agent that comes with 9.1 loads okay on 6.5,
but doesn't seem to do anything. Backups are as slow as the connections
without the agent.
