Full output of sensors-detect please. The SMSC LPC47M192 is supported
by two drivers: smsc47m1 for the fans and smsc47m192 for the voltages
and temperatures. Make sure both are loaded. If it still doesn't work,
please also provide the contents of /proc/ioports and check for error
messages in your kernel logs when loading the smsc47m1 driver.
