If I understand correctly, the problem with mem=XX and linux-2.4 is
when there are memory holes.  It is quite clear that old Linux
versions have the same problem with memory holes, since there is no
way to tell the kernel where they are.  So it wouldn't break anything
if grub would omit the mem=XX parameter when it detects a memory hole.
