If you haven't seen it, extensive posts on this can be found on another of the BMW forums about the drill and grease method - look for the 'Sticky Steering' post started by username 'bmwha'. Some have used grease, some oil - but introducing lubrication to the steering column does seem to have been successful in the long term for those who have done it.
NHTSA did do an investigation in 2010, but it was closed after determining that there was no safety issue that needed to be addressed. BMW has fixed a few cars for owners (at no cost) as goodwill, shared costs with others, and flat out refused to do anything for many others. There have been no recalls that I'm aware of on the E85 Z4 for this.
Fortunately this has not been an issue for me, but if I did have the problem I'd have no hesitation in drilling the column and installing a lubrication fitting. It's good to know there is a low cost and effective alternative to column replacement.
