This is just a followup post for those who would like to know how this
conversation developed. The details are in this ELRepo mailing list
thread:

http://lists.elrepo.org/pipermail/elrepo/2009-November/000102.html

In short, the write support offered by the kernel (hence kmod-ntfs) is
quite limited.  Alan Bartlett pointed to this section of the kernel
Kconfig file:

"The only supported operation is overwriting existing files, without
changing the file length. No file or directory creation, deletion or
renaming is possible. Note only non-resident files can be written to
so you may find that some very small files (<500 bytes or so) cannot
be written to."

Conclusion is, if you need to write to NTFS, you should use ntfs-3g.
