This is not true any more.  Doug Rabson and I modified
src/usr.sbin/mount_nfs so that it passes individual string options
via nmount() down to the kernel, which then parses the string options.

Doug added a fallback_mount() function which reverts to the
old behavior of passing a blob with key "nfsargs" for older kernels.

The Berkeley amd is the next big NFS mount client which needs
to be updated to use nmount().....but that code is messy. :)
