Final note from me on this topic, I expect: I just heard back from Nikon tech support. They acknowledge the problem and indicate no plans to fix it.
"You are correct, this is a known issue with this scanner. Please disconnect Firewire devices if Nikon Scan cannot find your scanner. Sorry for the inconvenience."
For what its worth, this seems to be an issue no matter which version of OSX you are using. I've just got a new FW800 drive and now I can't see the scanner when its plugged in. Doesn't matter whether its on 400 or 800 mode. As soon as its plugged in the scanner no longer shows up in System Profiler - the Mac knows there is a device plugged in but its not detected correctly. This is on an old Panther G5 (10.3.9).
Strangely enough I don't get the same problem when I have my DV camera plugged in via Firewire.
