Excellent, thanks, just what I was looking for :)

Is it really just as simple as creating the certificate, signing it with 
the right extensions, installing the proper rootCA on the windows 
machines , and configuring the windows supplicant correctly ?

Which would be

In authentication tab
Enable IEEE 802.1x authentication for this network
Setting EAP Type to PEAP

In properties
Validate server certificate
Authentication method EAP-MSCHAP v2
Checking the Root CA the certificate was signed with .

In Configure
Automatically use my windows logo name and password unchecked.

Or are there more weird windows things ?

Gah... never appreciated Mac OSX so much.

"oo  looks like your connecting to an 802.11x network , please enter 
your username and password, hmm you havent chosen to explicitly trust 
this certificate would you like to ?
.... Connected!"..... "and now i'm going to save your username and 
password in the keychain so you'll never have to go through this 
amazingly simple process ever again".
