Exactly this was the reason back then to not support non-contiguous set of CPUs. Inside qemu there is no reason why this shouldn't work, it was just hard to write on the command line. So after a short discussion we decided to drop this for the time being. If you have a great idea how to specify this (I think a comma will not work, because it will be catched earlier), I am all ears.
