I might try this... not too sure. But it reminds me of the racing game that I'm waiting for to be dumped (released in last week of February)... Sled Shred. It's a karting clone... for downhill sledding (bobsleds, tubing, etc) which you can play with your bum on your balance board!
EDIT: doh! further research shows Sled Shred was delayed to Q4 of 2010.
