It takes 4 points currently to make the front page, if your submission does not have those 4 points by the time it scrolls off the new page it will take a small miracle for it to be brought back.
Also notice that the 'new' page has a 'more' link at the bottom, you could do worse than to check page 2 and 3 as well to see if anything good fell through the cracks.
Voting up articles that have not made the front page past the third page of 'new' articles is unlikely to have much effect.
