Did Simon's patch get applied? I couldn't see it in any of the obvious 
places when I looked the other day.

I don't like this as a module parameter. That's not what module params 
are really designed for. It's better as DT so that it can be turned on 
and off for the individual devices, not system-wide.

mrf24j40 loads up fine under DT. There just isn't anything to configure 
(so far) other than the SPI.

Are there any other known boards which use the external amplifier 
besides the MB and MC (and MD and ME, which are the same as the MB and MC)?

Alex, I'm not sure how this fits with Simon's patch, as I haven't 
investigated it fully. I'd expect both implementations to be the same, 
but they're not.

Alan.
