In GRASS 5.4's ps.map there is the wonderful "sites" command with the size_att
option, but this doesn't exist anymore since sites are vectors now.

In GRASS 6.0 you could also (in addition to Hamish' solution) create eps
symbols that are already scaled (with R for example) and then use the vpoints
command (with $) to put them onto your map.

Or you write a script (or do it by hand if you don't have many symbols) which
creates a ps.map input file with a vpoints command for every symbol using the
"cats" and "size" options.
