Chip listing:
U1:
U2:
U3: ST Microelectronics M24128-BWP - "412A" "BWP" (128kbit I2C eeprom - tssop-8)
U4: Analog devices ADXL330 - "XL" "330K" "#0614" "3464P" (accelerometer - 16 pin LGA)
U5: suspected to be Microchip TC1027 - "628" "3322" (quad comparator -16 pin QSOP) - could possibly be a Mitsumi chip (the logo is similar)
U6: Unknown manufacturer - "U7849" "6Q19" (Likely Audio DAC chip, due to proximity to U7 Speaker amp, and lack of another chip to perform this function - 16 pin tsop)
U7: Rohm BH7824FVM - "H78" "2 4" "HN" (audio driver (speaker AMP) for mobile telephone - MSOP-8)
U8: Broadcom BCM2042 - "BCM2042KF8C" "C80830 P13" "788899 N1" (Broadcom bluetooth & 8051 - probably 88pin FBGA)
Other interesting things:
Crystal Y1, likely 24MHz
CCD Camera at the front of the PCB (8 pins, no distinguishing characteristics.)
Rumble motor off-board via wires (labeled "SEM 6923FB")
Large electrolytic capacitor (3300uF)
Connector at the base for nunchuk, classic, etc.. (6 pins)
More information on the Wiimote's attachment connector can be found at the Wiimote Accessory Bus page.
PCB is certainly more than 2 layers - probably 4 layer.
PCB has some text possibly marking the revision - "MDK 332V-0" followed by a small "N"
There are 3 fuses on the "top" of the PCB. (one larger one, and 2 smaller ones)
U1 and U2 are piddley little logic/transistor/voltage regulator ICs, U1 is 4 pins, U2 is 5 pins, and their captions are essentially meaningless.

Nunchuck PCB, Bottom View:

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)

Chip listing:
U1: Unknown manufacturer - "FNURVL" "A 405" "629KM" (custom processing chip? - TQFP48)
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)
Interestingly enough, the 2 analog sticks are mounted in opposite orientations...
The logic/control chip is roughly identical to the one on the nunchuck, the text only differs by 2 digits. ("629KM" instead of "633KM")
