It's tricky. We could also use a debconf question once, and remember the value to rewrite the conf file, but maybe that makes life to complicated. Empirically thinking, I'd say leave the patch as we have yet to meet actual infiniband users. But we need the big fat warning somewhere. README.Debian is a start. In a way, though, the problem is with the ibverbs library, and I seem to recall that its upstream author told me he'd change the behaviour. But I can't recall the details now...
