I have no knowledge of how Context's font stuff works. The first 
definition looks better to me, as one would not need to worry about 
the encoding while defining symbols (one needs to worry about the 
encoding while defining \textbreve etc, anyway). Though the second 
does have the advantage that it works right away, so there is no need 
to change the definition of \definemathsymbol.
what a mess

so ... up to you to define the missing pieces (maybe we should use \startmathencoding for this stuff)
