Aaargh. Sorry, shift reload helped. I kept viewing the cached version.

Yeah, ok I screwed up. The 'extra' files aren't really. The kernel source tree comes with a load of undefined symlinks, that get set by 'make dep'. So once you've built a kernel, there appears to be a whole load of new files compared to the same tree previously. My virgin 246 tree hasn't been built, but the volboost tree obviously has.

Try again now.
