it's not a correct assumption anymore; yes you can write the magic
sectors to the disk via the bios.... and the bios can even read the
format so that you can boot from it (but the bios does it on the host
cpu)

well it's basically pure software raid with bios boot support... 
(Note: with raid1 there is basically no cpu overhead so you won't
notice... :)
