Surecom 9001 and linux on PPC

Hi there. I've just bought a surecom 9001 usb because my airport extreme
doesn't work under linux. I've downloaded the at76c503a driver and
compiled under 2.6.3 (as well as 2.6.5-rc2-benh) on a Gentoo system and
it compiles and loads correctly. If I issue a "cat
/proc/bus/usb/devices" I can see listed the device, but after loading
the modules it just says (on dmesg and on kernel) that has been loaded.
But iwconfig doesn't say anything. The messages just say it has been
loaded but not that has detected the card or its mac address. I'm using
the last CVS version of the package. What can I do? I'm desperate...
hope you'll be able to help me!
Thank you!

Stefano
