Is grub your boot loader? If so I would hit "e" at the grub screen to edit 
your kernel and initrd lines. On my amd64 box I have symlinks in / that point 
to the actual kernel and initrd. I would try...

kernel          /vmlinuz root=/dev/md0 ro

and...

initrd          /initrd.img

Just a shot, not sure if that will work there or not.
