yeah, DRI does come with RedHat 7.2's Xfree, but it might not be as updated as you can get. I don't know for certain. But you can get binaries from sourceforge.net. There are also instructions there on how to get it working. I think it's as simple as tweaking your XF86Config-4 file, but I might be misremembering. Anyhoo, if there is any question as to whether or not it's actually accelerating 3D stuff, just fire up Tuxracer and you'll know within seconds. If you didn't install it originally, it should be on your RedHat CDs in rpm format. I guess that assumes you've got the CDs. If not, I can email the rpm to you, or something.
