Thanks for that pointer. I will look into getting Scott Burns fix
into the tree which should correct it. I will also ensure that
newfs scales back the number of inodes per cylinder group to
keep the total number under 2^32.

The long-term solution is to go to 64-bit inode numbers, but
that will have to wait for a major filesystem revision.
