VideoCore reports garbage in viewport geometry fields unless viewport was set previously by earlier stage boot loader. So when booting FreeBSD kernel directly from VideoCore's start.elf framebuffer intialization fails due to invalid vxres, vyres values. Make sure we request viewport to be equal to physical resolution Submitted by: Sylvain Garrigues <sylvain@sylvaingarrigues.com>
