Quoting myself:
I can reproduce it, with both i2c-i801 and i2c-parport, so it's not
related to a specific driver. I'm currently performing a bisection on
2.6.17-rc4-mm1 to try and isolate the culprit. It seems to point to

Stephen, Greg?

Look at the error return from class_device_register. I bet
it was working before because the class_device_register wasn't
checking something, now it is and that exposes a bug that has
existed in i2c since sysfs support was added.

I can make up a more verbose version if that helps
