I vaguely remember doingn some research in this area a few years ago
looking a report on linuxppc-dev about this and the kernel's unaligned
access was dependant on the device being given a mtd point function
which means the device is directly accessible in the cpus address space.

I don't remember much beyond that and don't have time to dig.  I am
just an observer with respect to linux mtd.
