The IBM part number is 73P2505 on box, and 93P3475 on adapter (IBM uses more than one part number for this adapter)!
Brand new in sealed box. This is the IBM B/G adapter based on the Atheros chipset NOT the Intel 2200. This is the OEM adapter in some models and is an option for CTO and customized ThinkPads.
I've been using these units in an R30, an R40 and a T40. They work flawlessly and the WiFi LED works on the R40 and T40 (R30 doesn't have one) and the on-screen display (Fn-F5) works on both the R40 and T40.
The R40 needed the no-1802.com hack, but the T40 and R30 (surprisingly enough) didn't need it. They just booted right up.
I installed the IBM software/drivers first and the card was automatically recognized and worked.

This is a great internal WiFi adapter and reportedly uses less power than the Intel 2200-based adapter. Maybe less than the A/B/G version, too?!
I bought several to upgrade personal laptops, but now have a few spares. I am also selling one on eBay, here's the link for more info and pictures -
