looks like a working fallback for non-js users. After digging deeper one learns that this noscript-code is not working at all as it is, because one actually has to add the rec param.
I suggest changing it to the following (rec param given and short explanation):
<!-- Piwik -->
<noscript><p><img src="http://piwik.mysite.org/piwik/piwik.php?idsite=2[b]&rec=1[/b]" style="border:0" alt="" /></p></noscript>
<!-- End Piwik Tracking Code -->
Another alternative would be to remove the noscript completely then: There is no need for non-working code.
