Well not intentionally. :p The thing is that the kernel hack is only one piece of the puzzle. You need a file with the remote code mapping you wish to use. Check Frank's readme for an explanation of this, and look in that directory for some examples. By default I think the kernel includes some codes for Pioneer steering wheel remotes, but it may not (by default) map the button you wish to use to the exact functions you want. That is left to the user, but Frank gives some good help in the README with the hex codes the Pioneer remotes send out.

Anyway there's always a risk in installing a kernel. The very worst thing that would happen is you'd have to re-do your 2.0 upgrade.
