Did you get the one called kmod-ntfs from livna.repo? Or there is also the linux ntfs project (you'll need to google it, I don't have a link).
The easiest way is from livna. yum install knod-ntfs but you'll need livna repo installed. (And I think you'll need a kernel newer than the one that comes with FC5). Read this
yum section. Read through firefox and thunderbird and into ATI and Nvidia ro the livna repo section. I recommend reading the whole thing.
It's a good step by step guide for all your extra needs.
