That limitation is specific to Linux-md I believe; doesn't grub uses the
BIOS to access the drive(s)?  If so, I think BIOS-RAID (and of course
hardware RAID) should be transparent and work fine.

Old-grub also didn't support newer Linux-md metadata formats, so that
should be explicitly mentioned (I don't know about grub2).

I don't speak for anybody but myself - that's enough trouble.
