[PATCH 162] fbdev monochrome lines

[Geert Uytterhoeven <geert@linux-m68k.org>]

screens. This removes the bogus horizontal lines next to the logo.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
