Duplicated i8042 devices in lshal

[Andrey Borzenkov]

hal-0.5.12-0.rc1.2mdv2009.1

I noticed that I have two keyboards in lshal output. Walking backward it 
tracks down to:

{pts/1}% lshal --show /org/freedesktop/Hal/devices/platform_i8042_0
udi = '/org/freedesktop/Hal/devices/platform_i8042_0'
  info.linux.driver = 'i8042'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'Platform Device (i8042)'  (string)
  info.subsystem = 'platform'  (string)
  info.udi = '/org/freedesktop/Hal/devices/platform_i8042_0'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'platform'  (string)
  linux.sysfs_path = '/sys/devices/platform/i8042'  (string)
  platform.id = 'i8042'  (string)

{pts/1}% lshal --show /org/freedesktop/Hal/devices/platform_i8042
udi = '/org/freedesktop/Hal/devices/platform_i8042'
  info.linux.driver = 'i8042'  (string)
  info.parent = '/org/freedesktop/Hal/devices/computer'  (string)
  info.product = 'Platform Device (i8042)'  (string)
  info.subsystem = 'platform'  (string)
  info.udi = '/org/freedesktop/Hal/devices/platform_i8042'  (string)
  linux.hotplug_type = 2  (0x2)  (int)
  linux.subsystem = 'platform'  (string)
  linux.sysfs_path = '/sys/devices/platform/i8042'  (string)
  platform.id = 'i8042'  (string)

Both are absolutely identical; how comes HAL enters the same device 
twice under different UDI?

It is not the fist time I noticed it. I already reported duplicated 
batteries. It does not happen every time; unfortunately I do not know 
what triggers it.
