Okay, guess I misunderstood what you wrote before. The patch below for 2.6.23 should do what you want (and more besides). It forces the USB Persist feature to apply to all persist-enabled devices, whether they were unplugged or not. There's no chance of this getting accepted into the official kernel in such a simple form, but at least it will allow you to do what you want.
