I would love to, but from my googling it sounds like preseeding software raid + LVM is a black art of some sorts. Lots of chatter on google, but not much solid info. If anyone has any examples of this, I'd love to see them. TBH, I don't think the many raid device issue is a breaker, it just "looks" messier then a nice hardware raid /dev/sda device.
