Well, if you really only want to find bugs in kernel code (specifically linux drivers) there was a recent white paper that came out that used Dynamo Rio to instrument and analyze the kernel. You can (I think) trigger simulated events to the kernel and compose a sort of fuzzing environment against any given kernel code.
The problem with Dynamo Rio is there's currently really no Pin++, so if you were to wish for something like a mature taint analysis or symbolic emulation (or whatever else...) facilities that you can embed within your own custom analyses it would be a costly manual labor operation.

Hacking a driver is easy? :)

There is only one approach to understanding any code. Reading the code
and understanding how different things interact. If you have doubts
you can always ask here.
Read Linux Device Drivers? Though that will still not prepare you
for actual code. Eudyptula Challenge?

Just running the kernel might not always point out bugs.
