This is the warning printed by the pciproxy code when the
driver tries
to enable the DMA bit in the device's PCI config space. DMA
is *not*
supported, because we can't keep the device from writing
arbitrary
memory in the host system. Drivers must use PIO to access
the device
(and more important: read back data).

Have you applied the patch to the to the AppleAirportExterme
kernel
extension that forces it to PIO? For more information, check
this thread
