Could you please use wp_enqueue_script() instead of just echoing the script tag directly?
if(get_option('google-chrome-javascript')){
add_action('wp_enqueue_scripts','kws_google_chrome_js');
}
function kws_google_chrome_js(){
wp_enqueue_script('chrome-frame','http://ajax.googleapis.com/ajax/libs/chrome-frame/1/CFInstall.min.js',false,'1');
}
