Watch out for the boomerang effectI'm just throwing darts, hoping one will stick.

Seriously, that's quite unlikely to work. If you're not really sure, it pays to measure your steps.
As I think I suggested above, I recommend a kernel upgrade rather than recompiling. Don't add any repositories to the package manager, because all you want to change is the kernel. I think there is a post higher up this thread explaining how you can work out exactly which files to download. The procedure is probably simpler.
