arm - Gumstix with an e-ink screen

I really want to develop on a gumstix with an e-ink display, but $3000 for a development board is a bit steep for me right now, especially since I just want to get a prototype out so I can see what the market is like.

As a work-around, this is what I have in mind:

• Buy a Kindle



• Buy a gumstix with a dev board


• Hook up the Kindle display to dev board using clever soldering

This is what I want in the end:

• Low-power, easy to read screen (text viewing)


• Wifi-enabled device


• More than 4 GB of persistent storage


• Touch enabled device (I can get by without this)


• Preferably color, but monochrome is ok

I am really intrigued by the persistence of the e-ink display without using battery...

Is it possible to use the e-ink screen with the gumstix? If not, is there anything else I should be looking into?

EDIT:

I think I can root the Kindle and install my own OS on it, but I won't be able to easily add parts to it (say USB ports, audio ports, etc). The gumstix is really the way to go.

Legal:

From what I read in the EULA, it is a violation to disassemble the Kindle, but the only thing they can do is revoke access to the Kindle Store and revoke use of any eBooks or services downloaded. There is no mention of penalties or fines for violating the EULA with respect to hardware. Since I am not developing this as part of a company, I don't think there is anything they can do legally.

Even so, I just want to know if it can be done with existing hardware and software. If I plan to market something with Kindle hardware components (which I won't), I'll definitely talk to a lawyer first.
