I personally dislike that.  I think the tool show should everything that 
it *could* do assuming
proper kernel, etc.  Then, if it turns out the current running kernel 
can't do that, it could just
give an error:  "This feature not supported in your current kernel.  See 
[url] for info on when
features were added to the kernel."

That way, the user can see all the possible goodness out there, and 
perhaps be inclined to upgrade
to a later kernel if that gives them a feature they'd like.

Thanks,
Ben
