PEAP authentication failure with ACS

I had a reauthentication problem which was fixed by the hotfix reported on http://support.microsoft.com/?kbid=885453. The hotfix repairs a compatibility issue between MS PEAP and "third party radius servers" (i.e. ACS). Unfortunately, the patch gave me a new problem. Now the initial authentication fails. The second attempt works but the quiet time has to expire before I get network connectivity. Anyone know of any hotfix that fixes the hotfix?

Which version of ACS are you using?

I am using ACS version 4.0.

The switch was running 12.2.25-seb4. After I upgraded to 12.2.25-SEE1 the problem went away.
