How much overhead does polling involve? [A particularly problematic case is when polling is failing - I've occasionally seen speedtouch modems where polling fails every time (not sure why) and for some reason this increases system load considerably, which is why the speedtch driver has a dynamic polling interval]. If polling overhead is basically nothing, then this change is OK with me. Otherwise the next simplest thing to do is to have a short polling interval when the line is down, and a longer one when the line is up.
