>Description:
The Airport base station can only use this chips in shared
memory mode. The kernel configuration was being ignored
for this chip and in some cases using the iobase for the
shmem base. If shared memory set in the kernel then this
fix listens to it.
>How-To-Repeat:
Netboot an Airport base station and it will fail without
this. Code for the netboot coming later.
