NE is confused on AI

[Daniel Brotsky <DCB%MIT-AI.ARPA@MIT-MC.ARPA>]

A little while ago I switched to NE on AI so I could use the
JOBDEV device.  I then reported to bug-emacs that Auto Save had
suddenly refused to write auto-save files under the visited
filenames.

Well, I've done a bit more research and I find that, on AI, EMACS
has FS DD FAST non-zero for DSK: and AI: (as it should be) but NE
has FS DD FAST zero for these devices.  That's why my auto-saves
were using Auto Save Filenames instead of the visited file.  Can
NE on AI be fixed?
