are you displaying a raster map at all? if so what happens if
you set the null value (nv) to some color with r.colors?
maybe the "setcolor" instruction helps with that? (I keep
on meaning to check if that still works)

another idea along the lines of the rectangle decoration is to
use v.in.region to make a big box, then display that as the
last/bottom vareas layer.

if it was to be added to a ps.map instruction I'd guess it
should belong to the "border" one as "fill_color" or so.

ps- in case anyone finds it useful, I just added a page to the
wiki showing how to make graph paper with ps.map:
