Well, I don't fully understand this, the reasons why I think that the
last entries are bogus is that that (i) Marcus' laden program prints
an error message ("More than 4GB RAM not supported by L4" or some
such) and aborts when encountering this map, (ii) L4 fails to boot if
I use a less paranoid version of laden, and (iii) that the first three
entries seems to describe the memory in the machine that I am aware
of. But I may be too ignorant about PC hardware (the computer in
question is a dell latitude).

Thanks, I looked for such a command but didn't find it.

If it turns out to really be a bug in grub, I will.
