p.map use with floating point GRASS

GRASS users-

    Does anyone have recommendations for constructing
graphic GRASS map output from GRASS data that includes
a floating point raster map?

   I am getting segmentation faults with the raster map
I have created, and am unclear as to the extent of the
floating point update changes within p.map, p.map.new, and
ps.map; and any success reports using these map commands
within fp grass would be appreciated.

Thanks,

Eric Ohler
