A consequential amendment to the keyboard driver is also included. The VMU is a 'smart' flash chip where access is controlled by a microcontroller so that, for instance, flash erases appear to be transparent to the end user. The VMU does, however, show typical flash-type behaviour (eg phased writes) and the MTD layer and the chip work well together (eg in the way they handle apparent hotplug events during a block write). This version tidies up some style issues raised with version 2.
