> From the extensions docs:

"The spec is written as if the computations are
done on floating point values ranging from -1.0 to 1.0 (clamping is
specified where this range is exceeded).  The fact that NV10 does
the computations as 9-bit signed fixed point is not mentioned in
the spec.  This permits a future design to support more precision
or use a floating pointing representation."

Looks like you only need to clamp to zero here, if that really is the problem.
