* grub-core/loader/i386/multiboot_mbi.c (grub_multiboot_get_mbi_size):
	Take VBE info into account even if only text is supported.
	(fill_vbe_info): Take into account the case when only VGA text
	is supported.
	* include/grub/multiboot.h (GRUB_MACHINE_HAS_VBE): Set to zero
	on coreboot, multiboot and qemu.
