      Stuck after 3.
It seems it doesn't allow write mmio.
int probe_49fl004 (struct flashchip * flash)
{       
        volatile char * bios = flash->virt_addr;
        unsigned char  id1, id2;
        printf("3\n");
        *(volatile char *) (bios + 0x5555) = 0xAA;
        myusec_delay(10);      
        printf("4\n");
        *(volatile char *) (bios + 0x2AAA) = 0x55;
        myusec_delay(10);   
        printf("5\n");
        *(volatile char *) (bios + 0x5555) = 0x90;

You have to install it from source, I believe.
be sure to enable intel configuration types 1 and 2. The standard bios 
hides the 8151 bridge.
