It seems that the driver was changed without consideration to
backwards compatibility. The driver should still handle both the old
and the new prefix (since we keep this a stable ABI). The old one
should be deprecated but still accepted.

I.e. this is an OK change, but it's fine to hold off as a cleanup
until 3.18. The driver has a regression though, that needs to be fixed
for 3.17.
