What I customarily use, and which works, is the above except for the  
encoding:

\usepackage[LY1]{fontenc}

I don't remember whether LY1 encoding works out-of-the-box with  
TeXLive-2007, or whether I had to add support for it manually.

The problem, I think, comes from virtual fonts: LY1 doesn't use them,  
but T1 does. And given the line

> %!TEX TS-program = xelatex

you seem to be working on the Mac with TeXShop and the default XeTeX  
engine, meaning that XeTeX invokes implicitly the XDVI-to-PDF  
converter xdv2pdf, which doesn't support virtual fonts.

Have you tried invoking xdvipdfmx instead, which supports virtual  
fonts? Given your setup, quit TeXShop, go to ~/Library/TeXShop/ 
Engines/Inactive/XeTeX/ and move

XeLaTeX-xdvipdfmx.engine
XeTeX-xdvipdfmx.engine

to ~/Library/TeXShop/Engines/. Then re-open your test file in  
TeXShop, replace the line

> %!TEX TS-program = xelatex

by

%!TEX TS-program = xelatex-xdvipdfmx

and proceed. Do things change this way?
