The problems booting have nothing to do with 64-bitness: they have to do
with the old DOS partition table layout, which has no room for
partitions with either end located higher than 2Tb. If you want
partitions with either end higher up, you have to use GPT, which means
EFI booting as I understand it: horrible thought. I've managed to avoid
EFI for now by virtue of a hardware RAID controller which let me split
its array at the controller level into two logical devices, one for
booting, one very much bigger one (with no partition table at all) for
LVM.
