Says who? (Don't use LILO ;-)
Well, your kernels must be on a 0.90-superblocked RAID-0 or RAID-1
device. It can't handle booting off 1.x superblocks nor RAID-[56]
(not that I could really hope for the latter).
But that's just /boot, not everything else.
My expected device layout is also always the same, _with_ initrd. Why?
Not using ANY initramfs/initrd images, everything is compiled into 1
kernel image (makes things MUCH simpler and the expected device layout
etc is always the same, unlike initrd/etc).
Simply because mdadm.conf is copied to the initrd, and mdadm will
use your defined order.
Of course the same is true of initramfs, which can give you the 1 kernel
image back, too. (It's also nicer in that you can autoassemble
e.g. LVM-on-RAID, or even LVM-on-RAID-over-nbd if you so desire.)
