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=3Dy CONFIG_I2C=3Dy CONFIG_I2C_BOARDINFO=3Dy CONFIG_I2C_COMPAT=3Dy CONFIG_I2C_CHARDEV=3Dy # CONFIG_I2C_MUX is not set CONFIG_I2C_HELPER_AUTO=3Dy CONFIG_I2C_ALGOBIT=3Dy SMBUS I think is in the same category. From a search for smbus from within menuconfig: Symbol: I2C_SMBUS [=3Dn] = = =20 =E2=94=82=20 =E2=94=82 Type : tristate = = =20 =E2=94=82=20 =E2=94=82 Prompt: SMBus-specific protocols = = =20 =E2=94=82=20 =E2=94=82 =20 Location: = = =20 =E2=94=82=20 =E2=94=82 -> Device Drivers = = =20 =E2=94=82=20 =E2=94=82 -> I2C support (I2C [=3Dy]) = = =20 =E2=94=82=20 =E2=94=82 (1) -> Autoselect pertinent helper modules (I2C_HELPER_AU= TO [=3Dy]) = =20 =E2=94=82=20 =E2=94=82 Defined at drivers/i2c/Kconfig:76 = = =20 =E2=94=82=20 =E2=94=82 Depends on: I2C [=3Dy] = = =20 =E2=94=82=20 =E2=94=82 Selected by: I2C_PARPORT [=3Dn] && I2C [=3Dy] && HAS_IOMEM = [=3Dy] && PARPORT [=3Dy] || I2C_PARPORT_LIGHT [=3Dn] && I2C [=3Dy] && HAS_IOMEM [=3Dy] =E2=94=82=20 =E2=94=82 If I recall correctly, SMBUS and I2C work together on getting temps and fan speeds and such.=20 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.=20 Hope that helps. Dale :-) :-)=20
