NFS, SELinux, screwed up rights on /var/log -- I have never seen the error like this. > (--) PCI:*(1:0:0) ATI Technologies Inc unknown chipset (0x7210) > rev 206, Mem I talked with Dave Airlie about this and his conclusion was that most likely RHEL/CentOS 5.2 won't work with your card, but 5.3 should. If you are willing to try Beta, then it should be available from ftp://ftp.redhat.com/pub/redhat/linux/beta/RHEL5.3/ (of course, there is no support, it is beta, no upgrades, yadayadayada). For more information see announcement at https://www.redhat.com/archives/rhelv5-announce/2008-October/msg00000.html (it should be released January 2009). Best, Matěj Cepl
