Public bug reported:
Binary package hint: hal
When a Bluetooth mouse "disappears" then "reappears", whether due to the
mouse being switched off/on or due to a laptop suspend/resume cycle, HAL
seems to "leak" input device entries.
For example, after switching my Bluetooth mouse off/on a few times,
lshal shows:
udi = '/org/freedesktop/Hal/devices/bluetooth_acl_27605e077_logicaldev_input_2'

Of these, only the first one actually has the corresponding entry in
sysfs:

Every time the mouse disappears, Xorg eventually notices:
(EE) ThinkPad Bluetooth Laser Mouse: Failed to reopen device after 10
attempts.
and all lshal input device entries corresponding to the mouse disappear
- temporarily. However, they all reappear - along with the fresh one -
when the mouse is switched on again. Xorg is happy for a few times
around:
(II) config/hal: Adding input device ThinkPad Bluetooth Laser Mouse
(**) ThinkPad Bluetooth Laser Mouse: always reports core events
(**) ThinkPad Bluetooth Laser Mouse: Device: "/dev/input/event9"
(II) ThinkPad Bluetooth Laser Mouse: Found 9 mouse buttons
(II) ThinkPad Bluetooth Laser Mouse: Found x and y relative axes
(II) ThinkPad Bluetooth Laser Mouse: Found scroll wheel(s)
(II) ThinkPad Bluetooth Laser Mouse: Configuring as mouse
(**) ThinkPad Bluetooth Laser Mouse: YAxisMapping: buttons 4 and 5
(**) ThinkPad Bluetooth Laser Mouse: EmulateWheelButton: 4,
EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(II) XINPUT: Adding extended input device "ThinkPad Bluetooth Laser Mouse"
(type: MOUSE)
(**) ThinkPad Bluetooth Laser Mouse: (accel) keeping acceleration scheme 1
(**) ThinkPad Bluetooth Laser Mouse: (accel) filter chain progression: 2.00
(**) ThinkPad Bluetooth Laser Mouse: (accel) filter stage 0: 20.00 ms
(**) ThinkPad Bluetooth Laser Mouse: (accel) set acceleration profile 0
(II) ThinkPad Bluetooth Laser Mouse: initialized for relative axes.
Eventually, however, this seems to lead Xorg to run out of input device
slots:
(II) config/hal: Adding input device ThinkPad Bluetooth Laser Mouse
(**) ThinkPad Bluetooth Laser Mouse: always reports core events
(**) ThinkPad Bluetooth Laser Mouse: Device: "/dev/input/event9"
(II) ThinkPad Bluetooth Laser Mouse: Found 9 mouse buttons
(II) ThinkPad Bluetooth Laser Mouse: Found x and y relative axes
(II) ThinkPad Bluetooth Laser Mouse: Found scroll wheel(s)
(II) ThinkPad Bluetooth Laser Mouse: Configuring as mouse
(**) ThinkPad Bluetooth Laser Mouse: YAxisMapping: buttons 4 and 5
(**) ThinkPad Bluetooth Laser Mouse: EmulateWheelButton: 4,
EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(EE) Too many input devices. Ignoring ThinkPad Bluetooth Laser Mouse
(II) UnloadModule: "evdev"
(EE) config/hal: NewInputDeviceRequest failed (11)
At this point I have quote a few entries in lshal:
d...@detritus:~$ lshal |grep -c Laser
24
which means 12 entries, see sample at the top of this description.
Now, as I remove them manually from HAL:

[is that udi assymetry important?]
Xorg is finally told they're gone:
(II) config/hal: removing device ThinkPad Bluetooth Laser Mouse

and after the mouse is cycled once more, Xorg is happy to see it again:

I think this is a HAL bug; please let me know if there's any more info I
should attach.
