  VGA_MAP_MEM translates to ioremap() on some architectures. It makes sense
  to do this to vga_vram_base, because we're going to access memory between
  vga_vram_base and vga_vram_end.

  But it doesn't really make sense to map starting at vga_vram_end, because
  we aren't going to access memory starting there. On ia64, which always has
  to be different, ioremapping vga_vram_end gives you something completely
  incompatible with ioremapped vga_vram_start, so vga_vram_size ends up being
  nonsense.

  As a bonus, we often know the size up front, so we can use ioremap()
  correctly, rather than giving it a zero size.
