Yikes.  The a stupid and quite serious bug in d-i.

with lilo it's safe if the LV is created with the continuous flag, for
grub I'm not sure whether it has LVM support these days, I implemented
support for LVM1 ~5 years ago but it got lost (and I don't have the
patch anyore either)

Or any other of the partition formats that work.  E.g. all the SGI Altix
systems with >2TB volumes (which is probably all of them) use IRIX disk
labels.
