I haven't read all five pages of answers, so maybe someone has told this before. the history of music is full of bands with bad or really bad players, but in the end, what really matters to people are the songs. we musicians appreciate the good chops of every one of the members, but the public have a more global look. if you are a band of friends doing good music and you have fun with these people around you and the you like the music, you should stay. this drummer has gave birth to this band, and he deserves not to get fired.
there is something significant in your story, that is his bad drumming was not a problem on small stages, and it is now that you are starting to succeed that concerns you. that means to me that the problem is not his drumming (because it was not a big issue for you either), so that you have changed the way you see things, but the music is probably the same. so if his drumming is really so bad, you should talk to him, not as a musician, but as a friend. if you are getting bigger and bigger, spend time rehearsing and make "the band" sound better.
sadly, all type of realtionships go to the "replacement" attittude instead of working together, and music escapes not to this tendency.
