Doesn't help with the KVM requirement, and still only provides a 4GB address
space for any single process.

ZFS should work on i386.  As far as I know there aren't any killer bugs that
are architecture specific, but I'm no expert. Unless your aim is to learn about
ZFS I personally wouldn't bother with it on an i386 system: you'll almost
certainly get a lot better performance and a lot less grief out of UFS under
those conditions.
