Err, make that 2.6.30, sorry. While the infrastructure was there since
2.6.25, the way I converted the sound drivers doesn't fit in what
earlier kernels considered acceptable (the checks on which driver
methods were implemented was a little too strict IMHO). So the
converted drivers can only be used with kernels >= 2.6.30.
