If resolution is the issue, don't convert the vector maps to rasters. 
Instead, use the PostScript file directly; if PowerPoint can't handle
PostScript, then convert it to a *vector* format which PowerPoint can
handle (Maybe it supports WMF?).

If you can't find any way of importing the data into PowerPoint
without rasterising the vector layers, then use a higher resolution. 
Calling "gs" directly (rather than using pstopnm) will allow you to
exercise more control.
