I posted about this yesterday.  The only way that I see to make it
100% is to use some assembly routines that could be allocated dynamically,
and that would call a 'generic' callback.  The true callback could be
stored in memory somewhere, so that you don't have to lose the last 
argument in the case of a 9 argument call back.  I'm not sure when I'll
have a chance to work this out, but if anyone's interested, fptr.e
is a good place to start.
