I've given this quite a bit more testing today.

It works fine qemu-kvm 1.0 -> qemu-2.0+patch (cirrus vga)
It works fine qemu-2.0+patch -> qemu-2.0+patch (cirrus vga)
It doesn't (yet) work qemu-2.0+patch -> qemu-kvm 1.0 (cirrus vga).

The reason for this is (at least) that I need to emulate the
broken versioning of the mc146818rtc timer section, as writing
it correctly confuses qemu-kvm 1.0. Therefore please don't bother
testing migration back to 1.0 yet.
