I came up with this cross-browser function for Zoom Google:

http://diveintomark.org/projects/greasemonkey/accessibility/zoom-google.user.js

function addGlobalStyle(css) {
    try {
        var elmHead, elmStyle;
        elmHead = document.getElementsByTagName('head')[0];
        elmStyle = document.createElement('style');
        elmStyle.type = 'text/css';
        elmHead.appendChild(elmStyle);
        elmStyle.innerHTML = css;
    } catch (e) {
        document.styleSheets[0].cssText += css;
    }
}

Though this probably requires that the page has a stylesheet at all
(Google did, so I didn't care).
