With modern tooling we should align the partition or DM device correctly
so the swap starts on a properly aligned boundary. But I don't think
anybody has looked into hooking the swap stuff up with the I/O
topology. I'm also not sure the swap code is flexible enough to deal
with units that are bigger than page size.
