Thinkpad wireless options

[Ben Liblit <liblit cs wisc edu>]

I will soon be buying a new IBM Thinkpad X40, and am considering my 
wireless options.  It would be very nice to be able to use 
NetworkManager on my new laptop.  More generally, NetworkManager seems 
to be a good torture test for distinguishing the really horrible drivers 
from the not-so-horrible drivers.

My X40 wireless options include:

	- IBM 802.11 b/g Wireless LAN Mini PCI Adapter
	- Intel Pro/Wireless 2200BG Mini PCI Adapter
	- IBM 11a/b/g Wireless LAN Mini PCI Adapter II

It's hard to tell just from these names what the real chipset is, and 
therefore which Linux driver would be used.  But if any of you have good 
or bad experiences using NetworkManager with any of the above, please 
let me know.  If one of these is known to use a badly broken driver, I'd 
rather find that out *before* buying.

Bonus points if one of these is well supported by a standard 2.6.10+ 
kernel driver rather than an inconvenient nonstandard driver downloaded 
from some project web page.

Thank you!
