OLPC upgrades

A patch isn't really appropriate but generally speaking I:

- Followed Mitch Bradley's instructions for tar-ing /dev.
- Replaced the initrd with a 3 liner using busybox that just mounts  
NAND and calls switch_root.  This involved undoing all the version  
stuff in the filesystem.
- Replaced rc.sysinit with a 30 line script that starts the services I  
want and mounts the required points.
- Removed the entire SYSV runlevel system.

I was learning about all this stuff as I did it, but it still didn't  
take that long.  And I have a lot of plans to make it even faster.

A few things don't work right, like I'm still trying to figure out why  
there are no network interfaces...But If anyone would like to see the  
scripts I'd be happy to share them.
