This is not a bug about a problem I found, but about a problem I think
can become common with the introduction of >2 TiB disks.

A while ago, I found that bochsbios (the free BIOS used by bochs and qemu)
had an incomplete implementation of LBA48 that caused a fatal error when
attempting to access a disk sector above 2^32:

Although this was fixed, seening how often it happens that we find bugs in
all the variety of BIOS implementations out there, I would expect some of
them will have similar problems.

Of course, there's no way for me to reliably find how common will this be;
perhaps we're lucky and bochsbios is the only one which had this, but I
think it's better to be safe than sorry, so I would propose that D-I avoids
possible problems by generating a separate /boot in the default partition
layout whenever the disk size is above 2 TiB.

Excuse me for not providing a patch, but I'm totally clueless about how the
auto-partitioning heuristics work.
