To be honest, I'd like to not continue to experiment with reserved-memory on 
this board, I've already spent way too much time figuring out how to not make 
the phone crash under some circumstances, and now it seems relatively stable.
I might've even put my eMMC into some weird read-only mode where any write to 
it just weirdly fails (also original software) by writing to random locations 
in the RAM (or well, what Linux thought was non-special RAM).

Luca
