I have looked through the hooks and I can see there is a typo in the dmraid hook file.
Open up /usr/share/initramfs-tools/hooks/dmraid, so: sudo gedit /usr/share/initramfs-tools/hooks/dmraid
look through that file, on line 23 it says force_load dm-raid45. This should of course be dm-raid4-5.
So if you change that to dm-raid4-5 then save it and update the initramfs with the above command it should work. The rc14 version uses dm-raid4-5.
I am attaching a patch which will hopefully get uploaded upstream.
