Just a note on an alternative route I have in mind

As far as I understand, there is a threshold for all screen updates that determines if a full refresh will be done. You can test this with Terminal + AnySoft Keyboard for instance.

With default keyboard height, scrolling output in terminal window will not cause screen reflash.

But if you decrease keyboard height such that terminal window grows, there will be lots of screen reflash.

I'd love to find a way to alter that threshold. On the Nook, this seems easy:

Digging into Nook firmware really seems to be worth a try!

They provide a lot more stuff than Sony like optimized EPD waveforms, bigger recovery image (1.5MB) etc.

But the Nook seems to be based on some TI OMAP board, not Freescale i.MX508 like the T1... It's an ERD79 Android image...

So the question is, which drivers / modules are compatible and which ones will brick the T1....
