Chip listing:

• U1: Unknown manufacturer - "FNURVL" "A 405" "633KM" (custom processing chip? - TQFP48)
• U2: ST Microelectronics LIS3L02AL 3-axis accelerometer - "1806" "3L02AE" "615" "MLT" (accelerometer - LGA-8)

Other interesting things:

• 5 pins seem to be used from the data cable, in a 6-pin header (These numbers match the numbers given on the Wiimote PCB)
• More information on the data cable and communications with the Wiimote can be found at the Wiimote Accessory Bus page.
