Thanks Daniel. I didn't update udev, but did update the kernel. Your 
method does work - thanks.  Also, using /dev/psaux works.

What puzzles me though is why /dev/input/mouse0 isn't created any more!
I used to have this rule:

BUS=="serio", kernel=="mouse*", SYSFS{description}=="i8042 Aux Port", 
NAME="input/%k", SYMLINK="input/trackpoint"
