I'm announing this in hope to help people in the same situation of me.
The driver used was xp64-5.3.0.56-whql.zip found on http://www.atheros.cz/ (http://www.atheros.cz/download.php?atheros=AR5006EG&system=2)

I don't know if maybe my card is a AR5007EG, which is the case of some people...

The ndiswrapper version is 1.52. Its dmesg messages when ndiswrapper module is loaded are:
