How is grub supposed to know to embed part_msdos.mod if it doesn't
realize that to get to md0 it needs to read sda2/sdb2 which are using
dos partition tables?

Currently unless I tell it explicitly to include part_msdos, it only
boots to a rescue shell and sees only the raw disks, no partitions,
no raid, no filesystems, no nothing useful.

If grub_device is an md raid, then you don't know enough about the
partition table needed to read that raid.

It currectly includes the right raid modules (after fixing the raid
versus diskfilter string in one place), the right filesystem modules,
but it is missing the partition table support and hence can't get to
the other modules.
