I took a look at the latest firmware image for this device. Although the GPL
code includes UBoot, there is no uImage header in the firmware, nor any
identifiable strings. This leads me to believe that the firmware is either
using a custom compression or it's encrypted.
I found a tear down of the device here: http://fahmu.net/tech/?p=130. If you
look at the first image, there is a small 10 pin header on the left side of the
board that is most likely JTAG. Immediately next to it is a 4-pin header that
looks like a serial port. This is probably the best way to get more info about
the device/firmware.
Without more information about the firmware we probably won't be able to
support this device. I might be able to get a hold of one though, I'll keep you
posted.

Looks like I can't get a hold of one of these devices; without further info we
probably won't be able to add support for this device.
Will mark this issue as accepted and leave it open in case someone can provide
more details...

Do you need access to the device or a file dump?

If you know how to connect to the serial port on the device it will probably
give you a root shell and you could get some info for us that way. But
otherwise, yes, I'd need the device to do this myself.

I will try to get to the serial port this weekend. One thing I have never known
is how to figure out the Serial port baud rate. Is there some trick besides
having the documentation or guessing to getting the right baud rate?

baud rate: I always guessed, faster to do that even if there were some way to
determine it before-hand

Yes, trial and error is the easiest/fastest/cheapest way to figure out the
serial port settings. If you happen to have an oscilloscope you can figure it
out that way too, but it requires math. :P Most serial ports use 115200, but
not always.
One thing that did get annoying for me was that most terminal emulation
programs (hyperterminal, minicom, etc) required me to go through several menus
or disconnect/reconnect in order to change the baud rate. So I wrote baudrate
(http://baudrate.googlecode.com) which is a tool that just prints serial port
data to the screen and lets you change the baud rate using the up/down arrow
keys, then saves the final setting to a minicom-compatible config file. But if
you aren't doing this stuff a lot, just guessing the baud rate in
hyperterminal/minicom is OK.
