This is part of Xen's ABI, so it isn't easily changed. You're right that getting monotonicity is a pretty ugly affair of doing something like "if (now < previous_return) return ++previous_return;", but its better than using the tsc. (Last time around, it was "Xen can't use the tsc because it can't ever be used as a stable timebase" - though I don't think that was you specifically.)
