here you go:

  # cat /etc/yaboot.conf
    boot=/dev/sda1
    partition=2
    #root=/dev/sda2
    root=/dev/mapper/mpath0-part2
    timeout=50
    install=/usr/lib/yaboot/yaboot
    enablecdboot
    default=Linux
    
    image=/boot/vmlinux
            label=Linux
            read-only
            initrd=/boot/initrd.img
    
    image=/boot/vmlinux.old
            label=old
            read-only
            initrd=/boot/initrd.img.old

  # sfdisk -l
    Disk /dev/sda: 36864 cylinders, 64 heads, 32 sectors/track
    Warning: The partition table looks like it was made
      for C/H/S=*/255/63 (instead of 36864/64/32).
    For this listing I'll assume that geometry.

As you can see from the commented entry for "root=" in yaboot.conf
i already tried using the non-dm-multipathed devices, but this wasn't
the cause of the problem.

Thanks & best regards,
