 Tested on XO-1.75, but likely broken on all models.

  * Plug sisusb device, boot
  * Sugar UI comes up on internal LCD, ignores external monitor
  * from a VT: systemctl stop prefdm.service ; systemctl start olpc-
 configure.service ; sysctemctl start prefdm.service
  * Sugar UI comes up on external monitor via sisusb

 olpc-configure is testing for the existence of /dev/sisusbvga0, and
 probably "winning" the race against the kernel module being loaded.

 Can olpc-configure wait for udev to settle?

 We could look into implementing this as something triggeredby a hal/udev
 event, but I don't want prefdm restarted on USB device insertion, and even
 on boot, we would still have udev+kernel module load racing racing against
 prefdm startup. I suspect that without a udev settle we're just moving the
 race around...
