ATI and DRI, It does work.

[Forlong]

Is any of this necessary in Hardy Heron?

No.

bluelamp999 - I'll look into it and see what I can turn up. I've only configured this for Single head. Although once configured for single head, I used the ATI Catalyst software to output to my second monitor off my laptop and it worked fine. Again, I'll look into it and see what I can turn up. I did see that once when I was doing it before, just don't remember how I fixed it.

prshah - Thanks for the advice. I'll post up my commands and some brief output that they should return.

So far, I have had this work on all Single head configurations on desktops and laptops. These all used the Newer cards. The older cards can usually use the Xorg radeon driver and function properly. Most of the 9200 cards can use the radeon driver and get good graphics. This is mostly a fix for all us people with cards made in the last year or so. Below is my Xorg config file. You'll notice nothing special about it.

There is no special additions. The driver just works, once the kernel module is installed.

The purpose of DRI is for direct access to the video card to allow for fast speeds and good graphics. You basically can't run compiz or beryl properly without DRI. There are workarounds, but they fail to meet up to the standards.
