I have now gotten it to the point where:
Dom0=32, DomU=32 works (didn't work previously)
Dom0=64, DomU=64 works (worked previously)
Dom0=64, DomU=32 doesn't work (worked previously)

I'm completely baffled... the Dom0=64 + DomU=32 case is the one I've
been testing with all along, and it's only stopped working since I've
fixed up the structure alignment and told the backend that the frontend
is using the 32 bit abi.
