CentOS - Feb 2017 - mach64 driver, latest update in CentOS 6.8, symbol lookup error

Hello AndyBe,
    I download the ISO's and started the reinstall.  It went through all the
normal setup up to outputting the message that it was starting Anaconda.   Then
the screen went blank and stayed that way.  This is the same symptom as when it
is trying to start.  While the driver was not rebuild I suspect something that
accesses the driver added a call to xf86LinearVidMem which is not found in the
symbol list for the driver.

I am not sure where to go from here.  

I have a USB SVGA video adapter sitting in a drawer.  As much as I don't
want to, I am thinking of plugging that in.  That so much a long shot.  It is
designed as a second monitor.  I tried plugging a PCI video card (old) into the
expansion slot, but the system ignored it.  Either the BIOS is not interested in
other video cards or the slot is PCI-X only.

I would like to use this machine as my normal desktop as it has 2 processors
each with 2 cores at 3.6GHz.  It has 4 Gig memory with 4 empty slots and I have
a spare to use for parts.

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.

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 would recommend doing the reinstall, but choose *text* mode install.
You'd get through the install, and it might detect and build the video
driver correctly.

I installed with text mode.  It does not give you options and does a very
minimal install.  X is not included.  Neither is ssh/scp/rsync.  Fortunately yum
was included.  I did a "yum groupinstall Desktop" which brought in the
X server and the other necessary bits.  It did behave differently.  It just
loaded drivers vesa and modeset.  It tried to start and then got a segmentation
exception at address 0x0.  Last thing it tried to do was disable the keyboard
and mouse.

The monitor flags the input as bad with the message "Input Not
Supported".   I think I am following the wrong rabbit hole as it  never had
the chance to do any analysis as to what type of card it was.  Looking backward,
the mach64 that was identified worked correctly at CentOS 6.7.  I suspect that
the Xserver changed and the driver was not updated to match it.  This conclusion
fits with the fact that a previous poster on this thread said the driver was not
rebuilt and the original messages:
> > 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
Indicate a  reference to a symbol that does not exist in the driver.  Note that
the two messages were from separate loads of the OS.
