You could try something like this in your profile:

    [calc]
        my @choices = split(/\0/,$CGI->{yourselect});
        if (scalar @choices > 2){
            $Session->{errors}->{yourselect} = 'I said 2 choices only, dammit';
        }
        undef;
    [/calc]

I'd avoid JavaScript if I were you, as people can just switch it off.
Of course, you could use both.  Just don't rely on JS to actually do
the job.
