Unknow Device in XP After Upgrading BIOS

I just upgraded the BIOS in my T400 (2764-cto) from 3.01 to 3.11 (the latest) in preparation of an install of Windows 7. I'm currently running XP SP3, and after completing the BIOS upgrade I now see an Other Devices and Unknown Device icon in the Device Manager. I'm running the latest Intel AMT MEI, SOL and firmware, and I can't figure out what device is suddenly missing. Any thoughts or suggestions would be appreciated.
