Having tried harder, I confirm what Herb just said: accents come out  
OK after removing the above two lines from the patch (except for the  
error about \colon being already defined).

One *very* minor worry: that the accents will be taken always from  
cmr10, even if the Euler or Lucida math fonts are used. I don't know  
how this could be fixed. For Lucida, one could require lucidabr.sty  
to be called before fontspec.sty, and then using \let to do something  
like

\let\legacymathsencoding=\operator at encoding
\let\legacymathsdefault=\rmdefault

and then

\DeclareSymbolFont{legacymaths}{\legacymathsencoding} 
{\legacymathsdefault}{m}{n}

all this before the text fonts are initialized in fontspec.sty. But  
that's only for Luciuda, it's completely untested, and might be  
trashed by any possible \AtBeginDocument in other packages.
