As I mentioned here in this post, I quickly wrote up a little page chock full of links to Silicon Image datasheets. It's in my user namespace, since I really wasn't sure where to categorize it in the wiki, and because it's still a work in progress. Any suggestions on where to categorize this when it is done?
And here's the link: http://wiki.osdev.org/User:Quok/Silicon ... Datasheets
