I've been trying the balance board every few releases. The answer is no.
But it looks like there is hope! From other reading it seems that the balance board is very similar to wiimotes.
With a struggle you can get it to connect. There are two problems that I see right now:
1. The balance board always connects as wiimote #1. The wii does not expect that.
2. Support for multiple wiimotes needs to be working (it's really not right now, at least for me and a few others)
I'm waiting until multiple wiimotes are supported before adding an issue in the system.
