In this case, there was no call to objdump. Using strace I can see
calls to nm, but nothing about objdump.
This is getting mostly academic though as I do now have a new firmware
based on r12987 which does have a functional b43 driver in it. I say
functional because while it does work, it shoots the softirq up through
the roof while there is bulk data flying through the wireless interface.
I will post about that in a few mins.
