Sorry about that, I saw the nvraid module and got confused and thought that was supposed to handle it and there aren't modules for the other dmraid formats. Now that I think about it, that module is only for letting grub recognize such an array without the benefit of having the nvidia raid bios. It should be probing /dev/mapper/via_jehhchjje and noticing that is a dmraid array.
Could you run sudo blockdev --getsize64 /dev/mapper/via_jehhchjje
Also sudo dmsetup info /dev/mapper/via_jehhchjje
