Sounds like an LFS problem.  But even if you compile grub with support to
mmap big files or similar, the partition layout is GPT and the stage files
can't parse it.

I've been working to make GRUB 2 provide a solution for that.  GPT support is
already implemented (and supported by upstream), but it has to be enabled for
PC (i.e. non-EFI) systems.  I expect that next upload of grub2 will include it,
but it still needs some testing.  If anyone feels like it, my patch is at:
