the reason this can't make it into official CM is rather simple: to get rid of the bluedroid speed-up bug I had to replace the entire bluedroid bluetooth stack with bluez. This won't get officially supported by CM. Additionally I did a small framework hack to get the wifi ap working - which I can't push to CM as well as it depends on an older netd revision (although this would probably be fixable, but as long as bluedroid doesn't properly work I won't invest time into it, as I need to build from forks anyway). Last but not least I had to workaround an issue in the graphics subsystem which currently isn't compatible to CM, but I could submit the whole feature to CM I guess. The only one who could fix bluetooth properly is +Ricardo Cerqueira
I guess, he got quite the insight into the device. But he seems to have lost all interest in the P990, sadly. But he's brought so much to our device that I can't blame him. I got a couple more patches which I could submit to CM, but the 2x builds would still be substantially broken without fully working bluetooth. Additionally I tried to contact +Ricardo Cerqueira
via both IRC and Email and asked if he would be interested in the fixes, but he didn't answer. So be it.
Edit: Oh before I forget: The 2x CM kernel is bugged as hell, core features are broken, it will lead to multiple bsods and doesn't even impleent wifi & 3g powermanagement. This is LGs fault of course, but again arcee hasn't answered our questions about integration into CM.
