The tiny one is the Noritake GW128x32C-K610A-06. You need other hardware to do level conversion and stuff, see foxtrot's thread.

It's 19.2kbps and 1-bit, enough for ~4fps if you're just drawing the whole display every time. To get faster or grayscale Hugo was taking about basically replace the circuitry that drives it and just using the glass itself.
