Make option rom init more verbose 

When bringing up VGA by running the option rom it's sometimes
useful to get more information about the mode that gets set,
or the reason why the mode could not be set or a picture could
not be displayed. Also prefix the output from VBE mode setting
with VBE:

  Copying VGA ROM Image from fff0fd78 to 0xc0000, 0x10000 bytes
  Real mode stub @00000600: 867 bytes
  Calling Option ROM...
  int15_handler: INT15 function 5fac!
  ... Option ROM returned.
  VBE: Getting information about VESA mode 4161
  VBE: resolution:  1280x1024@16
  VBE: framebuffer: d0000000
  VBE: Setting VESA mode 4161
  VGA Option ROM has been loaded
