get the grid view by default - Sight 1.0.1 Wpshower Theme Part II

This is the follow up to this article. Unfortunately I spent a lot of hours trying to get this to work and didn't succeed.
When I wrote the other article I thought I had figured out...

So I can get the grid view by default, showing the right icons and all. But the one thing I couldn't do was to get the rollover-effect on the first load of the page. Since I suppose most people don't play around with the grid/list toggle... it is not that useful.
