That's the new DevFS -- /dev is created on-the-fly.  Symlinks are
not preserved between boots.  I just had my first experiences with
it too (see http://www.zepa.net/hypermail/elug/2001/03/0164.html).

The best way to fix it is to use the actual device in GPM and X.


   $ cat /etc/sysconfig/gpm 
   # Additional options for gpm (e.g. acceleration)
   OPTIONS="-m /dev/psaux"

   $ cat /etc/X11/XFree86-4
   Driver          "mouse"
   Option          "Device"                "/dev/psaux"

Was the disk from a SGI Irix system?

The pre-release kernels don't have the partition support for SGI
disk labels compiled in by default.
