Okay, here's a quick patch for fontspec.sty.
If Peter, at least, could try it out and report if it works generally  
(i.e., no other documents that you test break), I'd be most grateful.  
It certainly fixes the error resulting from

%%% test.ltx %%%
\documentclass{article}
\usepackage{fontspec}
\begin{document}
\fontspec{Lucida Sans Regular}
test \textbf{test}
\end{document}
%%%%%%%%%%%%%%%%

Here's the fix:
In fontspec.sty, v1.10, go to lines 161--163:

   \unless\ifdefined\zf at basefont
     \font\zf at basefont="\zf at fontname\zf at suffix" at \f at size pt
   \fi

Replace those three lines with:

   \unless\ifdefined\zf at basefont
     \font\zf at basefont="\zf at fontname" at \f at size pt
   \fi
   \zf at set@font at type
   \ifx\zf at suffix\@empty
     \ifzf at atsui
       \def\zf at suffix{/AAT}%
     \else
       \ifzf at icu
         \def\zf at suffix{/ICU}%
       \fi
     \fi
   \fi

(You can see that I don't like collapsing nested \fi's :)

What the code does is set the renderer automatically to whatever is  
chosen by default for the base font passed to \fontspec. It seems to  
work fine, and although I'm not 100% sure that I've tied up all the  
loose ends (all this [Renderer=] and OpenType [Script=] and  
[Language=] stuff has introduced some convolutions in the feature  
processing), I'm pretty sure it should work properly.

Stayed tuned for an eventual 1.11 which will include this patch  
amongst other small changes.
