A 4MB flash, 16MB ram version of this (same chipset) is already freely available for $15 as module (1), or $26 with a break-out board (2). You get 2xserial, a bunch of free GPIO's, 2xethernet, i2c, usb. OpenWRT has already been ported to this module, although you need to really strip it down to make it work reliably given the small amount of ram.

I was looking at the product picture for the module with the breakout board (2). It looks like the only available GPIO come from the 10-pin header at the top of the board. From what I could see it looked like there were only 6 free GPIO. Am I missing something? I did not see any datasheets or PCB layout files on their site.
