Version 1.64 of ps2eps that comes with MacTeX 2010 is still seriously flawed. Version 1.68 from http://www.tm.uka.de/~bless/ps2eps repairs all the problems, as far as I can see. In my experience, the optimal way to use it is with $hiresprecision=0.1 and the command line
ps2eps -l -f -g -r=3600 filename.ps
making use of the output from the HiResBoundingBox. The -a option is sometimes a little more accurate, but is slower. The older version had problems chiefly with bbox, which had numerous bugs. In fact, I can see no real reason to use bbox, as the gs computation of the bounding box seems very reliable now.
