[Arm-netbook] Repartitioning the internal flash

[Luke Kenneth Casson Leighton]

i can't quite believe i'm going to do this, but i'm going to:
* delete partition 3
* create partition 3 exactly same size as partition 2 (remember it
goes to block 1)
* dd if=/dev/mmcblk0p2 of=/dev/mmcblk0p3
* DELETE partition 2
* DELETE partition 3
* RECREATE partition 2 at exactly same size, exactly same point as "old" 3.

i'm taking a copy of the first 1024 bytes, just in case....
