Large PTE's aren't free either, though.  Cheap enough to implement but
there's some fragmentation that isn't easy to deal with in some
pathological cases.  The virtual space is pretty tight on some archs
already.

A lot of stock distributions load most drivers as modules so a machine well
stocked with devices may run into trouble.
