OLPC Firmware q4d06

Changes planned:

• touchscreen support for graphical test menu, <trac>11695</trac>
• calibrate a Raydium touchscreen, <trac>11704</trac>
• fix black-boxes regression in autorun-mfg-tests graphical test menu, <trac>11688</trac>
• add fs-update, <trac>11690</trac>

How to install a 2GB build on a 4GB or 8GB machine

• use fs-update to install the 2GB build,
• use fs-resize to resize the partition that holds the root filesystem,
• boot the build,
• use resize2fs /dev/mmcblk0p2 to resize the root filesystem to the new size of the partition.

An interim fix until <trac>10040</trac> is fixed.
