Well, KP49 bug is in SmartReflex efuse values for 720 and 805 MHz, so as long as you don't enable SR(or don't overclock) you are OK.

TBH on both devices I have SR works for 720 and 805 despite the above bug. But SR bug has nothing to do with DSP driver in KP49. What I really don't get is why people continue to ask the same stupid questions when it is clearly stated on the first page that KP49 is needed. Is it that the font is too small, or what?

On the other hand I start to think that I should remove script for n900 only installation. It seem that it brings more problems than it solves.
