What device/chip are you talking about and what driver do you want to use?

Currently there is no plan to add compatibility for kernel versions
older than 3.0 from my side, someone else planed to add support for
older kernel versions for B.A.T.M.A.N. Advanced, but I do not think this
will automatically cover your device driver.

We removed support for older kernel versions because we did not have the
recourses to support compatibility with so many kernel versions,
technically it should be possible to add support for kernel 3.6.25 again.
