IIS 7.0 Global CSS File

Question

I am setting up my new 2008 Server w/ IIS 7 and I am having trouble getting a global application style css file to apply to my web apps. So my app is in c:\inetpub\wwwroot\firmApps\applicationName and my css is in c:\inetpub\wwwroot\firmApps\applicationStyle/global.css.

This set up works fine on my production and test iis 6 boxes but not on the new server 2008 iis 7. If I change the app pool back from integrated to classic it works fine.

Things I have tried:

1. The Static Content feature is already turned on. http://stackoverflow.com/questions/800500/iis-7-0-with-pipeline-mode-integrated-doesnt-load-any-image-css-in-asp-net
2. Tried adding a build provider and http handlers w/ no dice. http://forums.asp.net/p/1247150/2295766.aspx#2295766
3. Folder permissions are fine.
