hi all and hi you, axel

my name is fabio and i'm an italian FC5 user with the default
2.6.15-1.2054_FC5 kernel in an asus notebook with the intel pro wireless
2200bg device.

I've had your same problem compiling the ipw2200 driver; could you please tell
me how did you solve the issue in object, eventually posting the link of the
patch (and some hint to help me)?

and do you think that i could not meet the problem compiling the last
kernel version as 2.6.16-1.2122_FC5?

thanks!!
