Version-Release number of selected component (if applicable): xorg-x11-6.8.2-1.EL.13.20 & kernel-2.6.9-22.0.2.EL How reproducible: Always Steps to Reproduce: 1.install a X850 Pro card 2. 3.

> Actual Results: kernel module does not get loaded and X blows up when trying > to use radeon driver. This is strictly a radeon 2D driver support issue, and does not involve the kernel. The "radeon" kernel module is only used by hardware which is supported by DRI, which is limited to R200 class hardware and older at this time. X11R7.0 is the first X.Org release to support this chip, which will be in Fedora Core 5, and also in a future Red Hat Enterprise Linux release as well. As this chip is not compatible with RHEL 4, users can use the "vesa" driver for unaccelerated 2D operation for the time being, until a new OS release containing the new version of X.Org is released which supports this chip. Another option, albeit unsupported, is to try ATI's proprietary fglrx driver, which may or may not support this chip. If you require additional assistance, please contact Red Hat support services at http://www.redhat.com/support or by calling 1-888-RED-HAT1 and a support representative will assist you. Setting status to "NEXTRELEASE" (RHEL 5)
