As far as I can tell, the current driver reads NTFS 3.0 filesystems (I
need a patch), for 3.1 (winxp) they seem to have changed stuff again.
There was some talk on the linux list about data corruption with 3.0
file systems, so I think they only support ro-mode.

Without this patch it only reads the first 512 bytes of each 4M block,
but I have no idea if this change is correct.
