Description of problem:
I just installed FC4 on an AMD64 system. I have a dual boot system, with XP, and another hard drive with mp3 on it, that is formatted as NTFS. It appears that FC4 doesn't come with NTFS support. When I do the mount command, I get this error:
[root@localhost etc]# mount -t ntfs /dev/hdb1 /home/windows
mount: unknown filesystem type 'ntfs'

I downloaded the rpm from sourceforge.net: kernel-module-ntfs-2.6.11-1.1366_FC4-2.1.22-0.rr.6.0.x86_64.rpm
I install it by:
[root@localhost installers]# rpm -ivh kernel-module-ntfs-2.6.11-1.1366_FC4-2.1.22-0.rr.6.0.x86_64.rpm
Preparing... ########################################### [100%]
package kernel-module-ntfs-2.6.11-1.1366_FC4-2.1.22-0.rr.6.0 is already installed

Then I try to load it:
[root@localhost installers]# modprobe ntfs
FATAL: Error inserting ntfs (/lib/modules/2.6.11-1.1369_FC4/kernel/fs/ntfs/ntfs.ko): Invalid module format

I am not sure what this FATAL error means and how to fix it. Any help?

Version-Release number of selected component (if applicable):
kernel-module-ntfs-2.6.11-1.1366_FC4-2.1.22-0.rr.6.0.x86_64.rpm

How reproducible:
Always

Steps to Reproduce:
1. download the appropriate RPM (listed above)
2. install it using "rpm -ivh <rpm>"
3. use 'modprobe ntfs' to try to install the module.
  

Actual Results:  The result is this error:

[root@localhost installers]# modprobe ntfs
FATAL: Module ntfs not found.


Expected Results:  It should have been installed as a loaded module so I can mount NTFS partitions.
