I thought about this too, but came to conclusion what first step is to
remove "version" from in-kernel API. It will reduce drastically desire
to add driver version to new drivers.

"There is no shame in doing the right thing, even if its too late.".

BTW, I hope that we all learned that allowing drivers to return free
string to users will always lead to disaster.

Thanks
