Subject: [PATCH] VBESetVBEMode() calls int10 0x4f02 to set a VBE video mode.
 This can be a     standard mode solely determined by the mode ID or it may be
 a detailed     mode with almost arbitrary mode parameters. The mode
 parameters are     passed to the BIOS in a memory area pointed to by es:di.
 If bit 11 in     the video mode is set this memory area is evaluated. When we
 don't have     such an area (passed to VBESetVBEMode() this function should
 unset this     bit for sanity reasons. (Bugzilla #3329)
