No way. I've tried doing the above, my partitions are /dev/cciss/c0d0p2 and 
/dev/cciss/c0d1p2, the second primary partition of both disks. I've tried to 
change the partition type from raid to 83 (linux) and did again the grub 
setup, but at the boot time the computer waits a lot and then drop me to a 
busybox shell. I can see a message that states that /dev/md0 cannot be found 
(it is the root filesystem). I've got a boot filesystem on both disk partitions, 
maybe grub cannot load /dev/md0?

Any clue?
