I reversed the "810-b43_no_pio.patch" patch as Jonas recommended
I also set CONFIG_B43_FORCE_PIO=y
the recompiled.

Just to be sure I also loaded with
    b43 pio=1

NOTE: there is no ssb module in OpenWrt.  perhaps its built in or
included in another module, I'm not sure

I still get the same OoM error, all be it a little bit latter.

The kzalloc() messages are now from the file pio.c - so I'm very sure
that its using polled I/O
