[PlanetCCRMA] nvidia drivers help

[Geoff King]

Hello,
I've been trying to get CCRMA kernel going on Fedora 14 x86_64 system.  
I've been using the stock kernel for a few months, but want to switch to 
the rt kernel.

My problem is that I can't seem to get the correct nvidia driver 
installed.  I've installed the CCRMA akmods package which is 260.19.29 
but my system already has the 260.19.36 driver  from RPMfusion such as 
xorg-x11-drv-nvidia-libs version 260.19.36-1.fc14.  It won't let me 
downgrade to the earlier version using yumex.  The only downgrade option 
in yumex in 260.19.12.

Could someone please give me a few pointers?
Maybe the CCRMA akmods package should be updated to 260.19.36 to match 
current rpmfusion?

Any help is greatly appreciated.
Thanks, Geoff
