No, you should only do "git bisect bad" if you find a CPU eater and "git bisect good" if you don't. For the non-booting kernels you should do "git bisect skip"; otherwise git gets confused as we can see here. Did you test v2.6.35-rc1? Does it have the CPU eater problem? If yes, please just reset your bisection git bisect reset git bisect start git bisect good v2.6.34-rc7 git bisect bad v2.6.35-rc1 and use 'git bisect skip' for kernels that don't boot or build.
