[Arm-netbook] Repartitioning the internal flash

[JLB]

Incidentally, am I the only one who is annoyed that with a meagre (by 
modern standards!) 2GB of internal flash, they still bothered to partition 
it into two large 'chunks' (mmcblk0p2 and mmcblk0p3)? Is there any sane, 
safe, reasonable way we could repartition this (i.e. to combine p2 and p3 
into one bigger partition) without ending up with a netbook-shaped brick?
