This is great news indeed, nice progress!
However, i have a question about CPU on Libre/jetbook.
https://wiki.mobileread.com/wiki/LCD_..._Reader_Matrix
says it is ARM9 200Mhz (ie ARM instruction set)
You say it is Dragonball, which implies 68000 instruction set, does it not?
EDIT: Answering my own question
http://en.wikipedia.org/wiki/Freescale_DragonBall
it appears newer versions of Dragonball are based on ARM9 and ARM11.
Obviously, since you got a custom image running on it, you are right.
Still, which exact CPU is it?
