You need to download the kernel patches from ftp.kernel.org, they will be
in /pub/linux/daemons/raid. Make sure you download the kernel drivers, they
will be at the top. The raidtools are separate, as I found out the hard way
:-). Once you have applied the patches, it should work. I just got a RAID-1
working last night.
