I just did this.

Note that I've got two inputs; dTo and dFrom.

dFrom has a minDate which defines the overall minimum (-3 months)
dTo has a maxDate which defines the overall maximum (today)

The get instance stuff I got from one of the authors when I emailed them
about something else.  The _getMinMaxDate function I looked in the
source...

 $(document).ready(function() {
            $.datepicker.setDefaults({
                showOn: 'both',
                mandatory: true,
                dateFormat: 'dd/mm/yy',
                buttonImageOnly: true,
                buttonImage: 'Images/calendar.gif',
                buttonText: 'Calendar',
                showAnim: 'slideDown',
                speed: 'fast',
                beforeShow: customRange });

            $('#dFrom').datepicker({
                defaultDate: '-1m',
                minDate: '-3m'
            });

            $('#dTo').datepicker({
                maxDate: 0
            });

            // Customize two date pickers to work as a date range
            function customRange(input) {
                    return {
                        minDate: (input.id == 'dTo' ?
                                    $('#dFrom').datepicker('getDate') :
                                    
$.datepicker._getInst($('#dFrom')[0]._calId)._getMinMaxDate('min')),
                            maxDate: (input.id == 'dFrom' ?
                                        $('#dTo').datepicker('getDate') :
                                        
$.datepicker._getInst($('#dTo')[0]._calId)._getMinMaxDate('max'))};
            }
    }
