>Description:
	when doing a mount_ntfs of sd0e, I get a userland error:

newlaptoy# !mou
mount_ntfs -o ro -i /dev/sd0e /mnt
mount_ntfs: /dev/sd0e on /mnt: Argument list too long
newlaptoy# mount_ntfs -o ro -a /dev/sd0e /mnt
mount_ntfs: /dev/sd0e on /mnt: Argument list too long
newlaptoy# mount_ntfs /dev/sd0e /mnt
mount_ntfs: /dev/sd0e on /mnt: Argument list too long

etc.

I also get a kernel printf:

ntfs_readntvattr_plain: POSSIBLE RUN ERROR
ntfs_readattr_plain: ntfs_readntvattr_plain failed: o: 0, s: 192072

The filesystem was created under NT 4.0 SP 6 & runs OK under NT.

An NTFS filesystem on wd0 mounts just fine.  It was created in
the past under NT 4.0 SP 4.  It is also much smaller:
% disklabel wd0 | grep NT
  g:  4188240       63       NTFS                        # (Cyl.    0*- 4432*)

>How-To-Repeat:
	1. create and format new filesystem on NT 4.0
	2. boot netbsd, do fdisk to create netbsd partition, 
           do disklabel to set things up OK
	3. newfs netbsd partition, mount it, things are OK
	4. try to mount NTFS partition, it fails as above.
