The irony is, I just realized I have such mini-PCI Wi-FI card - the very same model - in a drawer, given by a friend of mine after dismantling a broken laptop. If I ever end up with a complete laptop that I could fix for myself (or someone else) and would need a 9x driver for that piece of hardware, they're gonna hear from me badly.
(typos are gonna kill me someday...)
While I don't believe the search should be abandoned, I was able to track down this mysterious 126.96.36.199 version. And it is Windows 2K/XP only. So the Lenovo page is incorrect in claiming 9x compatibility, with that version at least.
A package claiming to be a "Beta" version of the 2200 drivers seems to also be 2K/XP only.
