I'm working on a site in Drupal, I have a font (Dax) that I am loading with Typekit, it is not displaying in IE8.
I did some research on Google but it appears that Typekit should work in IE8. I had been using the Typekit editor to add the font to CSS selectors. I tried adding the font name directly to the stack in my CSS file and using the special font names with weight included that are talked about on this page: http://help.typekit.com/customer/portal/articles/6855-using-multiple-weights-and-styles
It still does not work. I'm not sure if this is a Drupal related problem as I normally do not work in Drupal. It is also my first time working with Typekit.

Bad news, it doesn't work in (my) IE 9 as well. It should not have anything to do with Drupal. I've had problems with minified css/javascript and Typekit, but I can see you havn't compressed anything.
I see you are calling typekit as the last script in head. Try move it to the top. And use the advanced embed code instead. I would prefer to use a regular font-face declaration, but Typekit does not support this.
