However, I finally measured the resistance from the clock and data pins to the power pin, to figure out what size pullups were installed. Then, I searched the board for two resistors that were of that value. Just a little hint for next time

Yes, i did that, too. But when measuring the resistance between data and clk and the power pin, i could not get any values so i figured that there were no pull ups.
It almost looks to me like you soldered everything to the jack for the Nunchuck, not the end that goes into the WiiMote. That might be why you couldn't find any pullups, although I could be wrong
.
I soldered the Rs and diodes there because there's enough space and now i still can use the WMP with the Wii (except the jack for the nunchuk of course).

Like they say, great minds think alike, your's just thinks faster

Oh, I thought that there was some sort of microcontroller or something between the connection to the Wii and the socket for the Nunchuck. I guess the ports are connected directly to each-other, am I right?
-EDIT- Edited for clarity...

yes you're right, the ports are connected directly.

hey, just out of curiosity, will the NXTBee allow us to connect the WiiMote to the NXT? 'cuz the current WiiMote and NXT BT setup requires a computer in between, and if you want to skip the computer you have to wire up an adapter cable from the WiiMote directly to the NXT. Does anyone know yet if we can just do a direct WiiMote<->NXTBee?

XBee uses a very unique protocol, and is not BT. I don't see any way it would be possible.
