Keep it simple, apply the current timestamp in miliseconds to the URL:

// this fellow creates a link to the style sheet
// after the page has loaded
var link = $("");
link.attr({
        type: 'text/css',
        rel: 'stylesheet',
        href: 'http://example.com/style.css?' + (new Date).getTime()
});
$("head").append( link );

Please note that this is really a bad idea, if you're not going to change your stylesheet much, just replace the URL manually in the files. There are tools for that purpose available (sed under Linux-based systems)
