mouse config for PowerBook Pismo?

[Scott Frankel <leknarf@pacbell.net>]

Would anyone have suggestions for configuring the mouse for X v.3,
Debian Potato release?  This is for use with an Apple PowerBook
"Pismo" 2000.  When I launch X, I get some sort of desktop environment
(WindowMaker?) with the cursor locked dead in the center of the
screen.  It won't move with either the trackpad or an external USB 
mouse.

One suggestion I got was to change the /etc/X11/XF86Config file's
Pointer section's Device call.  i.e.:

  [/etc/X11/XF86Config]
  Section "Pointer"
	  Protocol	"BusMouse"
	  Device		"/dev/input/mice"    # was /dev/mouse
  EndSection

/dev/input/mice *does* exist; but unfortunately, this hasn't fixed 
the problem.  

Thanks
Scott
