The string 'Preview' does not occur in the file. The header looks like
this
%!PS-Adobe-3.0 EPSF-3.0
%%BoundingBox: 18 19 592 774
%%Creator: Wind/U Xprinter Version 3.3.1 (darwin) (Compile Date: Apr 18
2006 11:29:00) (bowman)
%%Title:
%%CreationDate:Fri Feb 22 08:18:04 2008
%%DocumentSuppliedResources: (atend)
%%Pages: (atend)
%%LanguageLevel: 2
%%EndComments
%%BeginProlog
There is a large bitmap in the file (or multiple tiles, I don't know
enough PS to know).
If I try to use the Postscript file printer instead, I get a Postscript
file, but I cannot open it with any other software I own (Adobe
Illustrator, pstopdf, etc.)

Ken,
from:
http://en.wikipedia.org/wiki/Encapsulated_PostScript
"... A fourth format known as a EPSI includes an ASCII-encoded preview
bitmap. This format allows for black-and-white previews only. It is
mainly used on UNIX systems. [...] An EPSI file will contain a line
starting %%BeginPreview: in the DSC prolog."
Does your .eps file have this %%BeginPreview: line?
Is it possible that this is what's happening, and that if you imported
your EPS file into another PS document the colour would magically
reassert itself?
Just a thought,
Chris
