nve(4) patch - please test!

[Martin Cracauer]

Sorry for being late.

The code that has been committed to -current works fine for me (DFI
NF4 SLI-DR).  It occasionally prints a timeout message on startup
(long into userland start), but it works fine and doesn't print more
messages. 

Performance is lower than Linux (about 70 MB/sec versus Linux which
gets the 108 MB/sec).
