Just discussed it with Marco on IRC, and he said we could load core.img in high
memory, like in 0x100000 right away.  This solves the size limit in memdisk
which I think is the source of the problem.

Of course, this collides with the OS load area, so we'd also need to add
relocation in loader, as described in the "grub_dl_unload_all()" thread.  I
do even have unfinished code for this, although it may take a while to get it
done properly (maybe we need to add features to memory manager or so).  Does
this work for you?
