X30 and WPA

Does any know how to get WPA working with the mini-PCI wireless card
that comes with the Thinkpad X30 ?

Ideally with GNU/Linux, but also with windows XP.
On the GNU/Linux side it's not clear what's needed to get any kind of WPA
support. On the XP side OTOH, I have installed the Q815485 update which is
supposed to provide support for WPA but to no avail and someone told me
that XP needs support in the driver as well, so I guess I need to upgrade
my driver, but I can't find any more recent version thn the one I have.
