With the prior state, working for Andre and others, it does not work onthe LifeView Trio (PCI and cardbus) and the saa7134 driver. Three guys Ithink reported it and Hartmut did wait with the patch for long andallowed about half a year for testing ... So, if we can't fix it soon, prior state of course counts and thoselater will have to use the patches further. Such a "fix" can always becommitted prior to 2.6.25 release.
