It looks mostly fine to me.  I have 3 suggestions:

I think it's better to #undef OHW after using it, just in case.

Perhaps GRUB_IEEE1275_FLAG_BROKEN_COLORS could be made more descriptive
(in the future we might find other, new, amusing ways in which colors can
break! :-)).  How about GRUB_IEEE1275_FLAG_CANNOT_SET_COLORS ?

Also, GRUB code style puts a newline before opening brackets.
