I2c is in the kernel. I use it to access my temps and such here. Just
a small snippet:
root@fireball / # zcat /proc/config.gz | grep -i i2c
# CONFIG_BMP085_I2C is not set
# CONFIG_SENSORS_LIS3_I2C is not set
CONFIG_MOUSE_SYNAPTICS_I2C=y
CONFIG_I2C=y
CONFIG_I2C_BOARDINFO=y
CONFIG_I2C_COMPAT=y
CONFIG_I2C_CHARDEV=y
# CONFIG_I2C_MUX is not set
CONFIG_I2C_HELPER_AUTO=y
CONFIG_I2C_ALGOBIT=y
SMBUS I think is in the same category. From a search for smbus from
within menuconfig:
Symbol: I2C_SMBUS

If I recall correctly, SMBUS and I2C work together on getting temps and
fan speeds and such.
Also, some folks use lm-sensors. I think it does the same but in user
space instead of kernel space. That's my understanding anyway.
Hope that helps.
