Anyway, in this case, the 'r' device isn't documented in the sa (4) man page, so I guess that was where my confusion came in, but after trying the /dev/nrsa0 device, Amanda seems to work like the champ it is. I'm assuming 'nrsa0' means non-rewind+raw device, which in retrospect is why the kernel was giving that error when I used 'nsa0' and Amanda probably tried to rewind it to check the label.
