This works:

Copy the folder /usr/local/texlive/2007/texmf-dist/fonts/opentype/ 
public/iwona into your ~/Library/fonts/ or the general /Library/ 
fonts/ and *restart*.

Then

\usepackage[math]{iwona}         %%% <-- this has to come before  
fontspec
\usepackage[cm-default]{fontspec}
\usepackage{xltxtra}
\setmainfont[Mapping=tex-text]{Minion Pro}
\setsansfont[Mapping=tex-text,Scale=MatchUppercase]{Iwona}
\setmathrm{Iwona}
\setboldmathrm{Iwona Bold}
\setmathsf{Iwona}
\setmathtt{Courier}
\setmonofont[Scale=MatchUppercase]{DejaVu Sans Mono}

You have to use the xdvipdfmx driver. Everything works *except* for  
the numbers, which come in Computer Modern, and I was unable to find  
out why (unless, of course, you use $\frac{\mathrm{1}}{\mathrm{2}}$,  
and I guess you wouldn't like to do that).

Best,
