This grub.cfg does not seem to insmod any RAID drivers.

Is there a /grub/grub.cfg file in the boot RAID array ?
If yes, what happens if you configfile it by hand ?

It is also unable to read the boot partitions by themselves for an 
"error: unknown filesystem."

What do you mean exactly by "read by themselves" ?

You must pass root=/dev/mapper/rootvgname-rootlvname
(double any "-" in rootvgname or rootlvname)
