Two comments.

1) Ghostscript itself has no problems with Mac, Unix, or DOS line endings. The
ps2pdf script shouldn't have any problems either since it does not attempt to
read a ps file. The epstopdf script can have problems with line endings
since it is a perl script written specifically for Unix and it does attempt to
read the eps file.

2) Ghostscript is quite capable of adding the Mathematica fonts when it is
converting a Postscript or eps file. You simply have to add the pfa 
Mathematica fonts to ghostscript's font directory and then modify the Fontmap.GS
file in ghostscript's lib directory. You should add these lines
/Math1				(Math1.pfb) ;
/Math1-Bold			(Math1Bol.pfb) ;
/Math1Mono			(Math1Mon.pfb) ;
/Math1Mono-Bold		(Math1MonBol.pfb) ;
/Math2				(Math2.pfb) ;
/Math2-Bold			(Math2Bol.pfb) ;
/Math2Mono			(Math2Mon.pfb) ;
/Math2Mono-Bold		(Math2MonBol.pfb) ;
/Math3				(Math3.pfb) ;
/Math3-Bold			(Math3Bol.pfb) ;
/Math3Mono			(Math3Mon.pfb) ;
/Math3Mono-Bold		(Math3MonBol.pfb) ;
/Math4				(Math4.pfb) ;
/Math4-Bold			(Math4Bol.pfb) ;
/Math4Mono			(Math4Mon.pfb) ;
/Math4Mono-Bold		(Math4MonBol.pfb) ;
/Math5				(Math5.pfb) ;
/Math5-Bold			(Math5Bol.pfb) ;
/Math5Mono			(Math5Mon.pfb) ;
/Math5Mono-Bold		(Math5MonBol.pfb) ;
to Fontmap.GS.
