Metronomefb and Deferred IO

I've posted a first pass at metronomefb. Metronomefb is a display driver for the Metronome E-Ink display controller. The patch also includes bugfixes for problems with deferred IO. I've uploaded a small video clip showing a Vizplex display with metronomefb on a gumstix running Xfbdev and remoting xeyes, xlogo, xclock and xloadimage. I'm very excited by the potential of this display technology. I hope to write more about it after Deepavali. To avoid any confusion, this E-Ink display is not related to the OLPC display (which is a LCD display).
