Disallow: /*?PageSpeed=noscript is correct. But sometimes Google ignore the robots.txt file. I recommend you to add the GET-parameter PageSpeed to the exceptions in Google Webmaster Tools.
Canonical is also a variant. and meta-tag robots (<meta name="robots" content="noindex, nofollow">) But blocking GET-parameters in GWT is the easiest way to block them, without any changes in HTML-code.
