In what context are they showing up as white?

Is it possible that they are being treated as transparent, over a
white background? E.g. "d.rast -o ..." treats nulls as transparent, so
the null colour doesn't have any effect. If you're using gis.m, raster
layers have the equivalent option, "overlay maps from other layers
(transparent null value cells)" enabled by default. OTOH, the option
is disabled by default in the wxPython GUI.
