After I saw a post about the cookie law (http://forum.cs-cart...__fromsearch__1) it was a big coincidence that i bump to it exactly the same time I was trying to give a more elegant solution to my clients.
So here it is for all 2.2.x shops
You uplad files to your root, you install via admin and you need just to edit one file:
1.open in your active skin index.tpl
2.add {include file="addons/eu_cookie/tpl/message.tpl"} right after the <body> tag (around line 24)
3.save and clear cache (both)
thats it!!
you get a nice warning on top of the site when you visit your site for the very first time.

All text comes with translation through the language tab in admin

and the link for the privacy policy is eddiable through the Addons setting screen.

If you run into problems with other jQuery driven Addons like banner slideshow then check in Addon setting screen the Jquery Conflict checkbox.
Works fine with 2.2.x Community, Pro, MVC and FF, Chrome ie8 & 9
Enjoy and report any problems.
