Subject: M:Robe 500i: More LCD initialization, and beginnings of support for
 QVGA as well as VGA on the LCD.  MPEGPlayer now works with reasonable
 performance on smaller videos, but YUV blitting persists after MPEGPlayer is
 left, some cleanup/changes to the initialization code.  This should be
 functionally equivalent for the ZVM, but the #ifdef's may need to be added
 back for app.lds.  Get the bootloader building again.
