FX4800 driver 340.106 will not install under RHEL7.5

I have several computers with old FX4800 video cards under RHEL7. The driver is listed as 340.106. When I try to install this driver after updating the RHEL 7.4 to 7.5, the driver install fails. It will not install under 3.10.0-862.2.3.el7.x86_64. However, if I back off to 3.10.0-693.21.1.el7.x86_64, the driver will install. Is there a new driver for FX4800 under this kernel. I can attach the nvidia log file is necessary.
thanks
