Hello Jason,

I'm sorry, but i haven't got enought knowledge to modify a driver by
hand ;(

I've just add in product list (l 101)

{ PCI_VENDOR_AIRONET,	0xa504	}


Now my mini-pci card looks to be reconize but i've got that on my dmesg:

an0 at pci2 dev 2 function 0: Aironet Wireless Communications product 0xa504
pci_io_find: expected type i/o, found mem
an0: unable to map registers


I don't understand this error.

Could you please take a look on this if_an_pci.c and look if you can fix
that. Maybe very difficult to do that without the hardware...
So if you just have a magic idea, let me know i'll test it.

Thanks in advance.
Have a nice day.
