So, I upgraded to a new kernel.  No problem.  I upgraded X.  Suddenly, xterm
won't run as a normal user.  xterm running as a normal user searches /dev/pts,
and comes up empty, so it aborts.  xterm running as root looks for /dev/ttyp*,
which works.  I can't mount /dev/pts:

# mount_ptyfs ptyfs /dev/pts
mount_ptyfs: ptyfs on /dev/pts: Operation not supported by device

?
