I am guessing that you are using an old version of the backport, and if
so, you might want to upgrade to 2.2.16 with the latest backport, or if
you can, try the 2.4.0-testn series. A lot of things have changed since
the version that it looks like you are using.
If you still have the problem on the latest copy of the driver, please
let me know (also know if this fixes your problem too.)
