Your boot partition is not by any chance a logical partition and
therefore would be (hd0,4) and not (hd0,0)?

Also: According to this bug [1], grub gained support for md metadata 1.0
in 2010. Maybe this has not yet been merged into Gentoo (or legacy grub,
at all).

You can try to use 0.90 metadata by specifying it while creating the
RAID with mdadm. I'm using it myself because AFAIK this is the only way
for grub to handle a single RAID containing partitions instead of
partitions containing RAIDs.
