No serial output whatsoever.
I've copied most of my code from the mainboard/via/epia directory, 
including this failover.c file; see below.

regards,
Daniel

failover.c:
#define ASSEMBLY 1
#include <stdint.h>
#include <device/pci_def.h>
#include <device/pci_ids.h>
#include <arch/io.h>
#include "arch/romcc_io.h"
#include "pc80/mc146818rtc_early.c"

static unsigned long main(unsigned long bist)
{
        /* This is the primary cpu how should I boot? */
        if (do_normal_boot()) {
                goto normal_image;
        }
        else {
                goto fallback_image;
        }
 normal_image:
        asm volatile ("jmp __normal_image"
                : /* outputs */
                : "a" (bist) /* inputs */
                : /* clobbers */
                );
 cpu_reset:
        asm volatile ("jmp __cpu_reset"
                : /* outputs */
                : "a"(bist) /* inputs */
                : /* clobbers */
                );
 fallback_image:
        return bist;
