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. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@25786 a95241bf-73f2-0310-859d-f6bbb57e9c96
