Q2D04 available for testing

[Mitch Bradley]

The firmware release candidate for Update.1 is ready for testing

The most significant improvements are in the firmware networking 
support.  OFW wireless networking is completely broken in Q2D03 due to a 
problem with the firmware in the wireless module.  Q2D04 works around 
that problem, and also fixes a few other issues that made association 
with wireless access points rather hit or miss.

The main thing that I would like for people to test is the ability to 
update the NAND filesystem wirelessly via the firmware.

Please see http://dev.laptop.org/ticket/2740 for details of the 
procedure the firmware uses to find the update image.

Basically, you need a signed image  (osXXX.img + corresponding fs.zip) 
on something that acts like a school server.  Acting like a SS means that it

* uses the IP address 172.18.0.1
* has a wireless AP whose SSID is either school-mesh-0, school-mesh-1, 
or school-mesh-2 .
* has an HTTP server that serves the osXXX.img and fs.zip files from the 
http root directory
