55d2446fe4 - USB mass storage device support and SCSI emulation layer ported from Qemu. 
USB device type 'disk' replaces the 'flash' stubs and uses the corresponding
  port option as the path to the flat image file. Successfully tested with
  OpenSUSE 10.2.
  TODO list:
    * plugging in 2 devices of the same type not supported yet
    * move all USB devices and SCSI emulation layer to separate files and C++
      objects
    * USB port runtime parameter 'optionX' should be handled in the code of the
      connected USB device
    * tests with several other guest platforms
- destructor deletes device buffer only when it exists
- handling of the USB error interrupt status bit fixed

883339c458 - call bx_gui->dimension_update() in after_restore_state() if a VBE mode is 
active (standard VGA and Cirrus modes don't need it, since it is handled in
  the normal screen update code)
