I'm reasonably sure that the article in question doesn't point to how
to do a png hatch symbol in ps.map, but rather points to a png screen shot
of the thing being done using an EPS pattern.   Radim's web site has a
bunch of PNG snapshots, and that article pointed at an old web site of Radim's.

ps.map lets you use a pattern file for fill that is very much like 
encapsulated postiscript (but does not support all features of postscript).  
There is an example of how to do it in the ps.map documentation under vareas.
What you want to do is make an EPS file with the hatch pattern.  Unfortunately 
there's no easy way to generate these things other than in your favorite text 
editor.  Getting the hatch pattern to look good might take a lot of iterating, 
but it can be done.
