Would you be able to drop the virtual demuxer patch(es) for now?

The fundamental problem here is that a physical IRQ is shared by wakeup
and IRQF_NO_SUSPEND handlers. Neither the virtual demuxer nor the flag
approach solve that problem.

Boris and I have spoken on IRC and have some ideas as to what we could
do, but no code just yet.
