Hell yes!
For me, the KP49 is some sort of wholy grail for the n900!
Finally, I don't have to worry about charging it every single day, and it runs rock-stable here.

@mooninite:
Have you ever considered to reflash your device (may backup your current config with backup-menu) only to determine if some issue caused by another application/tweak/whatever?
Don't get me wrong, I am not one of the windows-style guys who reflash their devices every week, but you're one of a very small number of guys where kp49 does not run stable and I think it would be important to figure out if it is really a kp49-related problem or not.

For my own part, I will never return to nokia-kernels at all.

Despite of this and to all other readers of this thread:
Have a happy new year!
