Sounds painful.
Pain will be where the existing qemu-kvm extensions collide with these refactored upstream devices (backend/frontend split specifically). That's where we have to merge very carefully. Haven't tried this yet, will give it a spin tomorrow or so. >From that point on, disabling the new stuff for now and at some point switching over from the old one should be simple again. BTW, PIT+HPET+speaker will cause similar issues for the same reasons.
