From your description, the band is doing well, as an act; the business is good. I get it that you're frustrated you don't have an equal partner in creating the groove, and it seems that will probably not change. That would frustrate me, too.
When I've had to work with a drummer with bad time, I've just gotten used to the idea that I'm gonna be the timekeeper. I laid it down, kept it steady, and when the drummer went off I maintained the pulse and waited for him to come back to me. Actually, that worked OK--but it wasn't as much fun as having an equal partner.
So my .02 advice is to accentuate the positive (the band is a good ride for you), and accept that you can't eliminate the negative (the limitation on the drummer's musicality is likely permanent).
