Hello Bob, looks like, the driver isn't rebuilt, take the centos 6.8 ISO and look how it goes.

After loading at release 6.7, the machine behaves normally. After running yum update, the X server will not start. Attempts to start it manually result in one of the following messages depending upon which OS is loaded. I initially loaded it as 64 bit and when that did not work I tried the 32 bit version of the OS. The graphics card is part of the motherboard so swapping it out is not an option. This is a server and there is no AGP slot. > > X: symbol lookup error: /usr/lib64/xorg/modules/drivers/mach64_drv.so: undefined symbol: xf86LinearVidMem > X: symbol lookup error: /usr/lib/xorg/modules/drivers/mach64_drv.so: undefined symbol: xf86LinearVidMem > > I yum grouperased the X Window System and Desktop and then groupinstalled it with no luck. I then changed my repos to point to the original ISO, but there were too many dependencies broken to get the system to groupinstall the X Window System and desktop. I tried forcing in just the driver, but it fails with a message about the driver being at a different release than the X server. > > I am planning to reload the OS and use the Yum Exclude to keep the Xorg pieces.

Not that that is likely to help.
