$(function() {
    var chart = new Highcharts.Chart({
        chart: {
            renderTo: 'container',
            type: 'pie'
        },

        plotOptions: {
            pie: {
                borderColor: '#000000',
                innerSize: '60%'
            }
        },
        series: [{
            data: [
                ['Firefox', 44.2],
                ['IE7', 26.6],
                ['IE6', 20],
                ['Chrome', 3.1],
                ['Other', 5.4]
                ]}]
    },
    // using

    function(chart) { // on complete

        var xpos = '50%';
        var ypos = '53%';
        var circleradius = 102;

    // Render the circle
    chart.renderer.circle(xpos, ypos, circleradius).attr({
        fill: '#ddd',
    }).add();

    // Render the text
    chart.renderer.text('THIS TEXT <span style="color: red">should be in the center of the donut</span>', 155, 215).css({
            width: circleradius*2,
            color: '#4572A7',
            fontSize: '16px',
            textAlign: 'center'
      }).attr({
            // why doesn't zIndex get the text in front of the chart?
            zIndex: 999
        }).add();
    });
});

You just need to provide the data as an array of two element (key / value) arrays. Specify an innerSize to get the donut style.

So your parameters will contain something like this:

...
data: [["Firefox",6],["MSIE",4],["Chrome",7]],
innerSize: '20%',
...

Here's a jsFiddle of a complete example.
