I can't say there's any absolute rule here -- of course the worst case scenario is that you can't get the page indexed at all. So if it is in the Google cache, then you're already one step up.
If a page seems stuck for too long compared to other pages on the same site, I would try giving it one new inbound link. An external link would be awesome, but even an internal link from a more frequently spidered page on the same domain would probably help.
I also siggest watching your server logs to see what Googlebot is and isn't requesting. You may uncover some clues that way.
