A small bit of terminology difference is being used, I think. Traditionally:
hardware raid: raid cards that handle all HDD io independently.
Bios raid / fake raid: what dmraid is meant for (or mdraid, for isw)
software raid: pure software/kernel solution; using mdraid.
now, as for booting -- as far as I know the only way to boot a full raid0 system is to use biosraid, since the bios cannot assemble the striped drives of a mdraid-0 in order to load the bootloader or kernel. yes this is probably a rare config (i would never run it) but if someone so chose, dmraid would be the tool for this job.
