Please. Pretty please.

I've started a merge myself, but then never found time to finalize it.

Carrying three basically identical drivers just creates a 
maintenance overhead for everyone involved.

The original idea of splitting the driver and just maintaining the 
latest has never really worked out; all fixes to the latest driver 
turned out to be applicable to the others, too.
So it just increased the workload for the maintainer for no real 
gain. I would _strongly_ vote for it.

Cheers,

Hannes
