Pretty please. I've started a merge myself, but then never found time to finalize it. Carrying three basically identical drivers just creates a=20 maintenance overhead for everyone involved. The original idea of splitting the driver and just maintaining the=20 latest has never really worked out; all fixes to the latest driver=20 turned out to be applicable to the others, too. So it just increased the workload for the maintainer for no real=20 gain. I would _strongly_ vote for it.
