The hypervisor will timeslice multiple vcpus onto a single vcpu. This patch doesn't relate to that; it's whether a Xen Linux guest's kernel can be preempted to reschedule processes while running under Xen. The normal xen-unstable or vendor Xen kernels don't support this, but the mainline kernel with paravirt_ops/xen support does.
