Need a quick answer about Wireless Mini PCI on R40

[redsi]

Hello!
I am helping a person to get a wireless card for his R40 (2681-46U), it is wireless upgradable and called IBM already. They said their IBM ABG card will be compatible but asking price is CDN$133...too expensive.

Anyhow, I look email and see a cheaper card as Intel Pro 2200BG Mini PCI.

Do you guys think it will be work with that R40? I need an anser quickly..thanks
