You will save yourself a lot of trouble if you
stick with hardware raid for the boot volume (i.e.,
the bios only sees a single device) and avoid LVM
altogeter for the root volume (assuming you put
/boot on /). Main reason is that if anything does
go wrong with LVM it's a pain to fix without LVM.

Until the X86 BIOS gets brains (and pigs floss...)
just use a simple partition for the root voume and
perhaps a second partition with a stand-alone rescue
system on the other drive. If you install LVM into
the root volume (e.g., /lvm) then yuo can at least
boot single-user and fix things.
