Fedora Core 9 PAE kernel install

[SiE]

Hi,

Hopefully someone can help. I've searched google and the forums and haven't found anything specific or helpful to resolve my issue.

I have Fedora Core 9 installed on a HP DC7800 which has an Nvidia graphics card. I installed 8GB of memory and so I installed the PAE kernel. When attempting to install the Nvidia driver it tells me I'm using a xen kernel. I've uninstalled the associated kernel-xen package and rebooted but it still seems to think it's a xen kernel. Based on the below output, I don't see why it still thinks I'm running a xen kernel. How do I get around this? Is there a PAE kernel without xen support? Is it possible to use 8GB ram without a PAE/xen kernel?

uname -a returns no "xen" in the kernel version:
2.6.27.21-78.2.41.fc9.i686.PAE

and there is no xen enabled option in my grub config:
default=0
timeout=5
splashimage=(hd0,0)/grub/splash.xpm.gz
