     My trackball is a USB 2.0 device, but the touchpad and pencil eraser
thingy are built into the machine.

     Well, here's my info for starters then.
	Computer:  Dell Inspiron XPS
		CPU:  3.4 GHz P4 w/HTT enabled
		RAM:  1 GB
		Graphics card:  ATI Radeon JN R420 Mobility M18 (*)
		Built-in pointing devices:  Synaptics Touchpad, GlidePoint
			eraserhead thingy
	External pointing device:  Logitech USB Trackball (**)

(*)  When X is started, the following messages appear in /var/log/message:
	info: [drm] Setting GART location based on new memory map
	info: [drm] Loading R300 Microcode
	info: [drm] writeback test succeeded in 1 usecs

However, near the end of /var/log/Xorg.0.log this is apparently reconsidered:
	(II) RADEON(0): [DRI] installation complete

...and a bit later...
	(II) RADEON(0): RandR 1.2 enabled, ignore the following RandR disabled message.

...and several "Initializing " lines later...

(**) The driver identifies the trackball as having 5 buttons, though in fact,
it only has 4.  This has been the case as long as I've been running FreeBSD
(i.e., since 5.2.1) and is not new to 6.3.

     Does it restart by itself?  Or simply crash on a signal 11?
