standard answer to this is:
get a fresh kernel either from the kernel SRPMS or kernel.org
then get the latest raid patch and raidtools from
ftp://ftp.us.kernel.org/pub/linux/daemons/raid/alpha/
patch kernel
install raidtools
edit files /etc/rc.d/rc.sysinit and /etc/rc.d/init.d/halt and
remove any reference to the (now obsolete) raid tools.

are you trying to upgrade from a single disk install to a raid,
this will not be that easy.
besides that root raid is even more painful since lilo cannot
load the kernel from an md device, you nedd a non mirrored /boot
partition, or you can try your luck with GRUB.

extended should not be mirrored
swap was unstable with old raid, it is stable now, so you can do it
I tested with kernel 2.2, not 2.0, (Ingo does it also work with 2.0??)

usually you do mkraid /dev/mdX
