As far as I know write support is STILL considered experimental and dangerous, and
from Linux NTFS RedHat Page
The driver in these modules is read-only.
But as far as read support goes, quoting my own web page Customizing the RedHat install at WinXP and RedHat 9.0 duel boot
( still trying to plug that damn thing hoping more people will get something out of it )
... RedHat source has ntfs support built into the source, you do NOT have to patch it ( but not their pre-built kernels ) ...
If you are comfortable building a kernel, I think that’s the way to go. You can still keep it all RedHat and get your ntfs read capabilities, and get a custom kernel to boot ( *nix humor ), just remember to enable it during the build. If not maybe it is time to dive into building your own kerenl, or try the RPMs at the link phishphreek80 recomended.

( by the way, I do not remember the prior kernel sources, but the latest as of this post, RedHat kernel-source-2.4.20-19.9.i386.rpm also alows you to enable write to ntfs, but I would not do it )

Hope this helps
