Experiments are fun :) Using the Fedora kernel config file to build vanilla-sources-4.1.8 on gentoo fixes the kernel panic. Apparently the upstream kernel devs changed the way 'make silentoldconfig' works so that it removes some important config options that virtualbox needs. Whatever they changed in the 4.2.x kernels fixed the problem.
