Creating Angstom kernel

Used ubuntu virtual drive
Followed instructions at to bitbake a kernel
Prepared SD card as described in
Followed instructions at for copying files to SD card

The boot partition wasn't enough so copied files from disk that came with it.  This is because the new BB-xM doesn't have U-Boot in NAND Flash so needs it on the SD card.
