I'm getting a 404 for everything under http://codedread.com/browser-tests/

There's the SVG Integration spec:

I've got a few actions to follow up on from the last SVG WG F2F, and as 
soon as I update the draft, we will be pushing for a First Public 
Working Draft on the spec.  It should answer some of the questions I 
anticipate you have.

The Integration spec doesn't (yet) include information about backgrounds 
or pointer events, but it will soon.  The scrolling thing would be odd, 
and certainly a bug.  In general, IE9preview seems to perform pretty 
well with the simple examples in SVG Integration.  I guess we need more

I hope that with a judicious combination of normative wording, 
informative references to other specs (HTML & CSS), filing of bugs, and 
general raising of awareness, we can get all these problems solved. 
Thanks for cataloging these issues, I hope you can help us drive them
