Remember --

To boot off a distributed RAID, it needs to be known, established,
turned "on" before the kernel loads.
Software raid is turned on after the kernel probes and starts running /etc/rc

Software RAID1 is not striped across disks, so it can be booted from.
All other software RAIDs on the drives are unable to be
individualized, and shouldn't logically be bootable.

I doubt you can do it with graid3 part of the kernel either.  This is
a big advantage over a hardware raid card... the card takes care of
the distribted peices of a file.

Sorry it wasn't a positive answer.
