Trouble implementing AdSense for Search

I want to implement AdSense for my web page. My problem is that I want to place it in a 170 px wide box.

Take a look at what happens http://surfdirections.com/images/stupidwrap.jpg

That is because the Google code has a NoWrap tag. Somehow, it seems that Internet Explorer overrides it, but Mozilla doesn't.

Now, I don't want to modify the AdSense code in order to remove the NoWrap tag because that is illegal. Are there any work-around-s for this so that the finished box will be exactly 170 px wide?

Second problem: also, the search results are a bit odd. I managed to implement them in one of my site's own pages, but notice that there is a huge gap at the bottom of the page, before the footer.
Did i mess something up in the html or is there another explanation for this?

Thanks
