  Modified files:
    sys/dev/syscons      scgfbrndr.c scvgarndr.c 
  Log:
  Fix syscons on amd64.  The SC_PIXEL_MODE commit from May 29th added a new
  function pointer to the vga render dispatch table and initialized it with
  vga_nop.  The problem is that vga_nop() is a varargs function, and the
  table declares a non-varargs function pointer.  On amd64 (and I think ppc),
  mixing varargs and non-varargs function pointers is fatal.
  
  Change vga_nop() and gfb_nop() from varargs to non-varargs do-nothing
  functions.  This stops the stack corruption that only happened on amd64.
