And worse one has to submit patches for the core kernel all the time.
And it's a single table, which means there will be lots of conflicts
when merging patches.

I think the new API approach is much better. Best would be if there
was a relatively simple standard way to add it to drivers (like a
standard module option). Then one could add it to a lot of drivers
with default to off. Users can test then and if it works the default
can be changed.
