Default I2C support broken in 260.19.36

The I2C support in the 260.19.36 driver package appears to be broken. The system is an HP Elitebook 8540W with an FX880M and the Dreamcolor display panel. This panel has some special options for color management that can be set via DDC. However attempting to do so using the I2C interface provided by the driver fails. I looked in the source code of the kernel interface (in nv-i2c.c) and put in some printk statements and it's happening when the function nv_i2c_algo_master_xfer is called.

I tried using some other software that uses the I2C interface and they all fail as well. This happened on both the stock Opensuse 11.3 kernel and with 2.6.37.
