Nokia, or better their contractor, forgot to fill the native display resolution
(1280x720) into the BIOS tables, which unfortunately does not allow to select
them via basic VESA BIOS functions. Given the unfortunate GMA500 aka. Poulsbo
driver situation we'd rather like to set the mode for more stable pieces of
legacy software blitting, for now.
