Same thing happens to me when I unlock gnome-screensaver. CPU utilization goes to 100% for hald-addon-input until I restart hal. I'm running on a Thinkpad Z60m.
Interesting syslog messages appear when this occurs: Mar 24 23:52:37 troglobite kernel: [ 7540.014311] input: Virtual ThinkFinger Keyboard as /devices/virtual/input/input18 Mar 24 23:52:37 troglobite NetworkManager: <debug> [1206417157.780176] nm_hal_device_added(): New device added (hal udi is '/org/freedesktop/Hal/devices/computer_logicaldev_input_6'). Mar 24 23:52:40 troglobite NetworkManager: <debug> [1206417160.570412] nm_hal_device_removed(): Device removed (hal udi is '/org/freedesktop/Hal/devices/computer_logicaldev_input_6'). Also possibly noteworthy, is that as I repeat this process, the "input" number increases. That is, done twice more, I'll get the above message for input19 and input20: Mar 24 23:54:58 troglobite kernel: [ 7657.892823] input: Virtual ThinkFinger Keyboard as /devices/virtual/input/input19 ...
