The problem is that GRUB doesn't properly follow the Linux/i386 boot
protocol.  Someone filed something similar in bugzilla a few months ago,
but I just got around to really looking at it and pinning down the
problem last night.  Basically, the problem is that grub needs to parse
the mem= and change where it loads the initrd accordingly instead of
just loading it at the top of its detected memory area.  I started
working on it then, but got distracted by sleep :)  Hopefully I'll get
around to finishing it in the next few days-ish.
