If your Cufón text is not displaying in ie9 beta, you have a two options.
Option 1
Update your cufon-yui.js or cufon.js JavaScript File (Link to JavaScript File “released 9/16/10″) replace the old file with the new, and upload to your server – make sure you back up first.
Option 2
Force IE9 to behave like IE8, by adding the following line to the header of your website, just before </head>.
<meta http-equiv="X-UA-Compatible" content="IE=8" />
