looks good – a lot more risers than I would have thought – are these JTAG like things for debug that won’t be on the final board or are they all for GPIO and I2C etc..?
I see there is a reset button, what are the other two buttons for?
I assume the total memory = 80M is just a preliminary thing until you get the real memory map worked out?
Yes, there are risers for peripherals (camera, LCD) that won’t be on the final board as people won’t be able to access them anyway (no end user access to the GPU). They are there for testing and development purposes. Some of the signals may go out to GPIO so you can attach things though, esp. camera.
The memory is shared between the GPU and the CPU so Linux won’t have access to the entire 128/256 memory map, the GPU can use quite a bit depending on what you are using it for.

What worries me is this little comment-pair:

Jamesh:
Uh, what? Why *can't* we access the gpu?

I can't disagree with you thereBut I guess they chose not to go with OMAP in aid to reduce costs? They are really making a push to market these for schools and developing countries.
I did not see that as I was skipping through the comments, maybe we would have to wait and see? They are still making lots of revisions ATM, as they want to make it much smaller. That comment still does not bode well
They have managed to get quake3 running though...

Is there a GPU binary?
Yes. The GPU binary also contains the first stage bootloader.
The processor is a 700MHz ARM11 processor and they will have 2 models with a choice of 128MB or 256MB RAM, sold at $25 and $35 respectively. Each will have 1080p HDMI out-out.

The Link I found this on: Here (Beware, some of the comments may cause *facepalm*)
I must admit, I have fancied the idea of owning a Beagle/Panda board to play with but one of these may have to take place next to my TV.
