NVIDIA i2c adapter?

[David Baron <d_baron@012.net.il>]

Getting this booting a 2.6.20-3 rt-patched kernel:

Mar 22 08:08:43 d_baron kernel: **WARNING** I2C adapter driver [NVIDIA i2c 
adapter 0 at 1:00.0] forgot to specify physical device; fix it!
Mar 22 08:08:43 d_baron kernel: **WARNING** I2C adapter driver [NVIDIA i2c 
adapter 1 at 1:00.0] forgot to specify physical device; fix it!
Mar 22 08:08:43 d_baron kernel: **WARNING** I2C adapter driver [NVIDIA i2c 
adapter 2 at 1:00.0] forgot to specify physical device; fix it!

I am using Nvidia's 9631 driver (last one to support old Geforce mx400 cards). 
I doubt this relates to the rt patch. There is nothing about this in 
Xorg.0.log and the driver is working correctly.

So ... how do I "fix it!" ??  (Or simply ignore it?)

I do not get this error for 2.6.18 kernels.
