OK, I've done that.  Unfortunately, it doesn't tell me much...  I get 
some msgs like
----------
pdf_font>> Input encoding "Identity-H" requires at least 2 bytes.
pdf_font>> The -m <00> option will be assumed for 
"/usr/share/fonts/bengali/lohit_bn.ttf".
---------
But those msgs happen with both the working font (as above) and the 
non-working fonts.  With the non-working fonts, I also get:
---------
** WARNING ** Embedding of font 
"/groups/opt/share/fonts/Rupali_01-02-2007.ttf" disabled due to license 
restrictions
---------
But my understanding is that this msg just refers to embedding of the 
entire font, and shouldn't affect the appearance of the PDF.

The non-working fonts also have a few msgs like:
---------
** WARNING ** No Unicode mapping for glyph name "bn" found.
No Unicode mapping available: GID=132, name=bn_initekaar
---------
I'm not sure what this means, but it only happens for three glyphs, so I 
wouldn't think it would explain why the entire Bengali text comes out 
looking like badly formatted roman.

I will attach the entire listing of output msgs below my signature.

Follows:
---------
\documentclass[]{report}
\usepackage{fontspec}

\XeTeXtracingfonts=1 %Suggested by Ulrike Fischer
%Bengali script:
%\newfontinstance\bengalifont[Script=Bengali]{Lohit Bengali}
\newfontinstance\bengalifont[Script=Bengali]{Rupali}
%\newfontinstance\bengalifont[Script=Bengali]{SolaimanLipi}
\newcommand{\bengali}[1]{{\bengalifont #1}}
\begin{document}

\bengali{রহিম্ কে ডাক্ বো}

\end{document}
---------
There are three fonts in there, two commented out.  The Lohit Bengali 
font (which comes with at least Red Hat) works; the Rupali and 
SolaimanLipi fonts both output roman glyphs formatted (I think) as if it 
were Bengali glyphs.  They're different roman glyphs in the two instances.
