One of the problems with NetBSD current (and before) for the Duo 
models is that External SCSI devices aren't supported because 
the Duo has two SCSI busses.   I was reading through the MkLinux 
pages today and found Apple's solution for this problem:

(from http://www.mklinux.apple.com/MkLCurrent/relnotes.html)

SCSI devices

For systems that have two SCSI busses (e.g., Power Macintosh 8100s), 
the two SCSI ID maps are logically merged into one. Devices sharing 
the same ID, but sitting on separate busses, are not supported. Only 
the device on the external bus will be accessible in such a case. 
Shadow drives are not supported.
