Initrd is what I'm using now and it works, but I'd rather get by without
initrd as I have no other need for it.

raid=partitionable is what I used before, but it doesn't work with these
new style partitions. The raid gets detected as md_d0, but no md_d0p1.

If this can't be fixed and these new partitionable arrays can't be used
as root without initrd it should be documented somewhere.
