These web pages contain a link to a binary
(http://3web.dkm.cz/modrak/WirelessDriver.kext.zip) and he/she offered to
share source code. I tried to email to request this version of the source
code, but could only guess at the email address and my message failed, so I
post publicly hoping he/she is on the forums.
Antoine, you might want to note for your "little guide to MAC address
customization" that this "modrak" version indicates it allows the Mac
Address to be set in Tiger. (I didn't test it yet because I just got Tiger
and am having an issue with the official Beta 6 (which I decided to try
first) not recognizing my card even though it did in Jaguar.)
