I turned on the firewire extensions and now NS works.

Early tests using the Stouffer gray scale show exceptional linearity down
to a OD of 2.25, then an abrupt flattening of the curve above that.  Using
OD axis, the sensitivity is actually highest between 1.6 and 2.25.  It
appears the sensor or the A/D has a negative offset.  Similar results are
obtained with Vuescan and NikonScan 3.0.
