I have a raster map that has a value in each raster area that I want to
show using ps.map. I have some of the regions that have no value and
the others are scaled for display using r.colors colors=grey.log.
However, when I output this using ps.map asking for legends on the
raster, all I get is a black box saying that it has no value.
I am using grass 5.0.3 on linux.
Anyone run into anything like this? Any way to get the legend to show
up with each value showing a different grey color?

Your categories have to be labeled in order to show up.
try r.support as a start.
5.4 man page:
"Adding the 'nodata n' instruction will prevent the "no data" box from
being drawn (category based legends only)"
