this "config.xbboot" if for build image that used by "xbboot"

1. at the root of openwrt folder:
	$ cp data/qi_lb60/conf/config.xbboot .config
	$ make

2. for now we need manully copy the "zImage" to bin/xburst
	$ cp build_dir/linux-xburst_qi_lb60/linux-2.6.32.16/arch/mips/boot/compressed/zImage bin/xburst/openwrt-xburst-qi_lb60-zImage-xbboot.bin

3. upload the image to Ben NanoNote
	a. boot Ben NanoNote to USBBOOT mode.
	b. sudo xbboot -u 0x80600000 bin/xburst/openwrt-xburst-qi_lb60-zImage-xbboot.bin

   then the NanoNote will boot. setup a password for ssh or use telnet to login NanoNote.
