Thanks, applied to the block branch.

This is quite obviously not the proper long-term solution, but I've had
a look at the code and considering that we'll only have one more release
candidate for 1.6, it seems to be too risky to do anything more involved
than this.

I'm going to revert this patch again for 1.7 and replace it by proper
snapshot=on support with driver-specific options.
