JavaScript solution, 340 chars when compressed (no eval, supports prefixed multiplicator and suffixed addition):

function comp (s, m, n, f, a) {
    m = parseInt( m );
    if( isNaN( m ) ) m = 1;
    n = parseInt( n );
    if( isNaN( n ) ) n = 1;
    f = parseInt( f );
    a = typeof(a) == 'string' ? parseInt( a.replace(/\s/g, '') ) : 0;
    if( isNaN( a ) ) a = 0;
    var r = 0;
    for( var i=0; i

Test code:

var test = ["3d6 + 12", "4*d12 + 3", "d100"];
for(var i in test)
    alert( test[i] + ": " + parse(test[i]) );

Compressed version (pretty sure you can do shorter):

function c(s,m,n,f,a){m=parseInt(m);if(isNaN(m))m=1;n=parseInt(n);if(isNaN(n))n=1;f=parseInt(f);a=typeof(a)=='string'?parseInt(a.replace(/\s/g,'')):0;if(isNaN(a))a=0;var r=0;for(var i=0;i
