I discussed that just with Martin, and looking at the code it doesn't look like we want to have GENERIC_HARDIRQS. If we would select that option it looks like we need to special case the common generic hardirqs code quite a lot, which is something we certainly do not want. However that's our result after looking 5 minutes into the code ;) So, if at all, it's not going to happen soon.
