[GRASS-user] v.kernel -- how to get useful results

I am not clear how to get useful results out of v.kernel. I have a vector
layer imported from PostGIS that has about 2.5 million points. I want to
make a high density raster to show where these points are clustered. I can
get the vector layer to display in GRASS just fine, albeit without
attributes because of http://trac.osgeo.org/grass/ticket/1274.

It's not clear to me, based on
http://grass.fbk.eu/gdp/html_grass64/v.kernel.html, how you can get it to do
something besides make a big, pinkish (salmon-red?) square?
