kmod-nvidia yum update problem

[Steve]

I get this error when trying to update kmod-nvidia package:

Test Transaction Errors:   
file /lib/modules/2.6.27.21-78.2.41.fc9.x86_64/extra/nvidia/nvidia.ko from install of 
kmod-nvidia-2.6.27.21-78.2.41.fc9.x86_64-173.14.15-1.fc9.12.x86_64 conflicts with file from package 
kmod-nvidia-2.6.27.21-78.2.41.fc9.x86_64-173.14.15-1.fc9.5.x86_64

which appears to be telling me that it cannot upgrade because the package it is trying to replace has a file by the same name. Isn't that the point of an upgrade?
I assume I am misinterpreting this.

Thanks,
Steve
