On x86 hardware I use initrd to initialize raid before mounting root.
The mkinitrd stuff seems to do that if a /etc/raidtab exists pretty much
automatically, although sometimes it helps to have the modules needed
listed in /etc/mkinitrd/modules. I imagine other architectures can use
the same method no matter what partition system is used for the raid
devices.
