sounds like your kernel doesnt support software raid 
	try to see if raid modules are loaded or can be loaded

	lsmod | grep -i raid
	insmod raid | raidtools | raidtools2

just commented on the 2 things that stuck out when i did my 2 second
reading pass

other important things to look for ..

	lilo.conf or grub.conf

	where root=/dev/md0   and boot=/dev/md0
