Written by Jaya Kumar.  Features: 

* use of defio. This enables it to work transparently with existing userspace fbdev applications, such as Xfbdev. I've been testing it with the unmodified Xfbdev from the beagleboard OE distro. 
* avoiding the use of a backbuffer and keeping memory use low use of URB queuing 
* looking like a typical fbdev driver and using standard edid and screeninfo structures 
Current disadvantages: 

* No compression or fills, etc - always sends raw pixels
