Well, libvirt just entered freeze for 1.0.3.  I think the best course of
action on libvirt's side is to patch 1.0.3 to flat-out reject any cpumap
that cannot be represented in a syntax understood by qemu 1.4; then a
future libvirt can re-add support for whatever new syntax qemu 1.5 deems
as appropriate.
