Hardware acceleration is not working on my new Intel G845GVSR motherboard with Slackware 10.1. Everything else is woring fine. I configured X using xorgsetup. These are my observations:

I also have an Intel i810 card in this laptop. It took a long time before I finally got my acceleration working. Not because its neccesarily compilcated, so much as i was fumbling blindly.

You're running the stock slackware kernel, right? ou need to compile your own, and make sure you compile the direct rendering module for your card. I reccomend looking through the options very, very carefully and making sure anything that looks related is there. I personally compile virtually everything I'm not using as a module, just in case. Its just using a small amount of hard drive space, which is not often an issue.

Your xorg.conf does look just fine, my config is virtually identical. Just go grab the latest kernel source from and compile with the direct rengering stuff and you should be good.

Look at my site here. It has the xorg.conf and kernel config that makes DRI/DRM work. Check them out /change what You need. And read this post. It should give you a good handle.
