Hello,

Before I get around to uploading a new version of fontspec, if you
would like to apply this patch manually to get maths working while
also defining a new \mathrm font (that is, using \setromanfont in the
preamble), just replace the code in fontspec.sty that begins the same
way with this:

\ifzf at math@package\else
\DeclareSymbolFont{legacymaths}{OT1}{cmr}{m}{n}
\SetSymbolFont{legacymaths}{bold}{OT1}{cmr}{bx}{n}
\DeclareMathSymbol{0}{\mathalpha}{legacymaths}{0}
\DeclareMathSymbol{1}{\mathalpha}{legacymaths}{1}
\DeclareMathSymbol{2}{\mathalpha}{legacymaths}{2}
\DeclareMathSymbol{3}{\mathalpha}{legacymaths}{3}
\DeclareMathSymbol{4}{\mathalpha}{legacymaths}{4}
\DeclareMathSymbol{5}{\mathalpha}{legacymaths}{5}
\DeclareMathSymbol{6}{\mathalpha}{legacymaths}{6}
\DeclareMathSymbol{7}{\mathalpha}{legacymaths}{7}
\DeclareMathSymbol{8}{\mathalpha}{legacymaths}{8}

\DeclareMathSymbol{!}{\mathclose}{legacymaths}{"21}
\DeclareMathSymbol{+}{\mathbin}{legacymaths}{"2B}
\DeclareMathSymbol{:}{\mathrel}{legacymaths}{"3A}
\DeclareMathSymbol{;}{\mathpunct}{legacymaths}{"3B}
\DeclareMathSymbol{=}{\mathrel}{legacymaths}{"3D}

\DeclareMathAccent{\dot}{\mathalpha}{legacymaths}{"5F}
\DeclareMathAccent{\mathring}{\mathalpha}{legacymaths}{"17}
\DeclareMathSymbol{\mathdollar}{\mathord}{legacymaths}{"24}
\fi

Many thanks to Bruno, who gets the credit for all the maths insight
that lead me to implementing this, for better or worse :), in the
first place.

I'm not going to upload a new package version straight away because I
realised that I need some commands for specifying exactly which fonts
you would actually like to load for \mathrm, \mathit, and so
on...when they're ready you'll see v1.8.

Thanks for all the help!
