You're thinking of it the wrong way. You just create a bunch of partitions and make them into raid devices. You shouldn't be using the entire disk or you will break autodetection. > I thought about lvm/evms, but I'm unwilling to make an initrd to > set it up (mounting root).

I typical create a small raid 1 mirror as /boot. Just be sure to install your bootloader on to all drives. Newer versions of lilo will do the right thing if told to use /dev/mdwhatever. -- There is no such thing as obsolete hardware. Merely hardware that other people don't want.
