For the Xilinx boards and Netduino I can write something quickly up
with basic usage instructions.

Would that be beneficial to have a section there (I'm just looking at
the ARM boards http://wiki.qemu.org/Documentation/Platforms/ARM) for
getting started?

If so how can I request edit access to the wiki?

I had never seen that before, thanks!
