Seems to work.  Both "modprobe" commands run with no error, and lsmod
shows this:

lsmod | egrep 'fuse|ntfs'
fuse                   49237  0 
ntfs                  196760  0

That's what I thought.  However, when I mount a partition created with
Windoze 2000, I can read files and directories, but not create or modify
anything.  Here's the actual scenario ( all commands performed as root):

# dmesg | tail

( no error returned )

Note the last line claims that hda5 is mounted with type "ntfs" and
"rw".

So, what am I missing, and where should I look ?
