versatilepb -usb -usbdevice wacom-tablet -show-cursor -m 64
-kernel 
/home/protocol/study/OE/angstrom-dev/deploy/glibc/images/qemuarm/zImage-2.6.25+2.6.26-rc4-r6-qemuarm.bin
 -drive 
file=/home/protocol/study/OE/angstrom-dev/deploy/glibc/images/qemuarm/Angstrom-x11-image-glibc-ipk-2009.X-stable-qemuarm.rootfs.ext3
