Marek, This looks good to me. It looks like this approach keeps the implementation entirely on the driver side of the interface, which is what I was hoping for. I had assumed that doing this type of operation in the driver would require assistance "from above" for saving and restoring state. But it seems like you've been able to do without that, which is nice. Let me know how it progresses.
