FWIW, it works on Linux too. I ran F10 i386 on a x86_64 kernel for a while.
About the only thing that doesn't work right is yum wrt kernel updates.

Indeed.
It would be nice if i386-userspace/x64-kernel were officially support..
such a setup does not make much sense, when your hardware supports
x86_64 not using it for userspace is a waste ....
