It is still ILP32, just running the cpu in 'long mode' to give
access to the additional registers and 64bit arithmetic.

But they've left 64bit items 4 byte aligned - which is a bit fubar.
I suppose they are trying to run apps with a standard i386 kernel
rather than an amd64 one.

I'd have thought an amd64 kernel would be easier to modify.
