Setting up PEAP authentication credential cache in XP

Hello Experts,

My XP Pro notebook connects successfully via a Cisco 350 PCMCIA WiFi card to our Microsoft PEAP MS-CHAP v2 802.1X  network.  The problem is, exactly every 10 minutes (I assume this is the WEP key turnover time), or whenever I roam to a new AP, I am reprompted via the balloon pop-up to re-enter my username and password, which do not change.  Needless to say, this is highly annoying.  

Supposedly, XP stores the PEAP authentication credentials in the registry, as in MS Q823731.  According to this article, in order to *remove* the cached credentials, it is sufficient to delete HKEY_CURRENT_USER\Software\Microsoft\Eapol\UserEapInfo.  My problem is the inverse, I want to *create* this key from scratch.  What are the details on this (these) key(s)?  Any ideas why this key doesn't exist on my XP?

I have seen similiar problems to this on my network, I installed the hotfix for 834565 and things got much better.  NOTE: this hotfix is not readily available (you have to request if from Microsoft support and it is considered experimental).  You can check it out at:
