I tried building nvidiafb into the kernel and using nvidiafb in the
"append" arguments. I set "CONFIG_I2C_CHARDEV=m" to get around the
immediate crash. When I booted, the nvidiafb driver worked, but the
crash still occurred when the DS1621 sensor driver came into
operation. The Code: listing is identical to the previous scenario.
CONFIG_I2C=y
CONFIG_I2C_CHARDEV=m
CONFIG_I2C_ALGOBIT=y
CONFIG_I2C_ALGOPCF=m
CONFIG_I2C_ALGOPCA=y
CONFIG_I2C_ISA=y
CONFIG_I2C_NFORCE2=y
CONFIG_SENSORS_DS1621=y
