There are kmdls for both 5.4 and 5.5, the kernels currently supported
are:

2.6.18-164.15.1.el5
2.6.18-164.15.1.el5.centos.plus
2.6.18-194.el5

The very nature of kmdls allow me to offer kmdl for verious kernels in
the same repo w/o one obsoleting the other.

But there is a rare code path in yum when both the kernel *and* the
nvidia release are bumped at the same time ("same time" means your
upgrades enclose both upgrade, so it looks as having been upgraded "at
the same time" from you yum's POV) where yum tries to pull the new
kernel instead of just upgrading as always.

In that case you can circumvent the logic by telling yum what to do
exactly, e.g. something like

yum install nvidia-graphics195.36.15{,-kmdl-`uname -r`}

In a nutshell: ATrpms does try hard to keep CentOS users happy. :)
