X41--unknown device: Intel 82801dbm lpc interface controller

[malone]

I've made a fresh, clean install of Windows XP on my Thinkpad X41 (non-tablet). I've got most of the devices drivers installed, but there's one that I can't figure out. Device Manager says I have an "unknown device" on my "Intel 82801 dbm lpc interface controller".

What is it? I thought it was the chipset, but I had installed the Intel chipset drivers (twice, just to make sure I had really done it), but it still reads as "unknown device" on "Intel 82801 dbm lpc interface controller".

Anyone know?

Thanks!

Yes, it's the IBM Security Chip (Atmel TPM). The driver for the device is here:
