This patch reshapes northbridge and southbridge inclusion. It selects

Browse source 
southbridge drivers in Kconfig.

* It includes initial superio code as well, but there is at least one
  error in the pnp_device.c/superio scenario left

* Fixed biosemu.c, vm86.c, pnp_device.c (sort of)

* Enable vm86 instead of x86emu per default for vga init for now. This
  makes VGA in qemu work. There might be a bug in x86emu or the compiler
  I am using. (gcc version 4.1.2 20070115 (prerelease) (SUSE Linux))

* Import isa-dma.c, keyboard.c and i8259.c from v2 /pc80, which was taken
  from LinuxBIOSv1 released from LANL under release LA-CC Number 00-34
  and using parts from the Linux kernel.

This patch makes vga and keyboard work in qemu. Yippie
