Linux Kernel upgrade to 3.x

Ok, linux kernel 3.12.6 compiles fine on the MBLD. And since I know how to debrick the device in case it doesn’t come up after the kernel upgrade (thanks to the excellent guide here in this forum), I could give it a try.

It would be easiest to start from an existing configuration, which is usually found in /boot/. But there is none… Does anybody know where the configuration file for the existing kernel 2.6.11-svn can be found?
