This problem shouldn't be specific to fontspec: in fontmath.ltx (one  
of the basic constituents of the LaTeX format), you've got also a  
definition of \breve:

\DeclareMathAccent{\breve}{\mathalpha}{operators}{"15}

Isn't the redefinition of MusiXTeX also colliding with this one?

Apart from that, the option [no-math] has just been added by Will to  
provide the user a switch to avoid, at the end of fontspec.sty, some  
redefinitions (taking some math elements from the Computer Modern  
fonts instead of the current text font) done to avoid some encoding  
problems with non-TeX fonts.
