two remarks

1) the usual problem with that idea is that if the kernel is externally
built, you can't do that (you don't even know if/where the config is)

2) I'd rather have it works similar to other dependancies, i.e having
the option removed and a comment telling me what I need to enable to 
have ktap available.

I recently had a similar problem with udev needing inotify, so the 
problem of the plumbing layer relying on some specific kernel feature
is probably a more generic problem... maybe a config option telling
kconfig where the kernel is ? That would be tricky with the way 
kconfig works, but that would be nice...
