Okay, I think the regression I saw was not because of this patch, 
but because of the issue I described as "BUG: getting erranesous 
command timeouts". I dunny why this bug didn't show up in 
rc2-wl, but now in rc3-wl. Maybe it has to do with the big 
kernel lock work that happens upstream, but that's just a guess.

However, I've splitted this patch into a functional part (the 
changed interrupt handling) and a search-and-replace part (the 
renaming & reorganizing of various #define's). Now it's easier 
to see what is happening.
