Axel Dörfler d16ddc579c * The boot loader now passes on its EDID info to the kernel, and that will
be put into a boot_item in frame_buffer_console_init().
* The VESA driver now supports gettings the EDID information as well; this
  is necessary now, since the app_server no longer takes over the mode the
  boot loader had chosen.
* Note, we might want to do this via vm86 instead in the future, and remove
  the kernel part again.
