Same problem here, solved with the "m-a" thing. Thanks for the solution.
BTW, this bug is ridiculous. Virtualbox broke for kernels -14, -15, -16, -17, etc. It's not possible that every time a new kernel is released, somebody has to remember updating virtual box drivers, or everybody's system will stop working, specially if the recompiling is trivial.
This bug should be changed to "keep drivers (virtualbox and any other) in sync with every kernel revision".
