In 2.1.82, but almost certainly in earlier kernels:

[root@gatsby davew]# mount -t ntfs -o umask=0444 /dev/hda1 /mnt/nt
[root@gatsby davew]# ls -l /mnt/nt
total 20
d--x--x--x 1 root root 4096 Mar 9 1997 Program Files

[root@gatsby davew]# ls -l /mnt/nt
total 16

So it seems that the bits for the NTFS umask option go "?rwxrwxrw",
which is a little unconventional.
