+	  If you say yes to this option, support will be included for the SMB
+	  Host controller on Acer Labs Inc. (ALI) M1535 South Bridges.  The SMB
+	  controller is part of the 7101 device, which is an ACPI-compliant
+	  Power Management Unit (PMU).
+
+	  This can also be built as a module.  If so, the module will be
+	  called i2c-ali1535.
+
+	  You will also need the latest user-space utilties: you can find them
+	  in the lm_sensors package, which you can download at
+	  http://www.lm-sensors.nu
