IR Proximity Sensor

Walking the /sys/class/ tree, there's something that identifies itself as an hsdl9100
<source lang="text"> root@castle:/sys/class# cat input/input3/name hsdl9100_proximity </source>
That's probably an Agilent HSDL-9100 Miniature Surface-Mount Proximity Sensor. Palm specs say the proximity sensor is used to turning off the screen when the phone is put up to your face as you are making a call.
