I found a solution I'll post here just in case somebody is in the same situation.
Every page inside google's docs viewer iframe has an id like :0.page.X, being X the number of the page. Calling the service like this

</code></pre>

<p>won't work (maybe because the pages ids are not yet created when the page is rendered?)</p>

<p>So you just have to add an onload attribute to the iframe:</p>

<pre><code><iframe id="iframe1" src="http://docs.google.com/gview?url=http://yourpdf&embedded=true" onload="javascript:this.contentWindow.location.hash=':0.page.20';">
</code></pre>

<p>and voilà, the iframe will automatically scroll down after loading.</p>

<p><strong>Note that page indices are zero-based. If you want to view the 20th page of a document in the viewer, you would need use the parameter <code>:0.page.19</code></strong></p>
    </p>
