South bridge is part of the Mboard's chipset. EG, VIA KT600,
nForce2, SiS M741, etc. As to function, start here
http://computer.howstuffworks.com/motherboard.htm
and keep lookin ;) Basically the chipset (north&south) bridge, is
just that... a bridge between the CPU and other parts of the
system.

That's fine, but if you're temps are in the normal range,
which yours are for an Athlon, you really only need to monitor
them while under heavy to extreme load. EG, using mprime's
torture test ....
'./mprime -m, choose 17' http://www.mersenne.org/freesoft.htm
.... in one console, start another and run 'sensors' frequently
to monitor temps. At least till they stabilize at an upper
limit. This is a very good stress test and is a first step if
hardware problems are suspected, eg, system lock ups, freezes,
random reboots, failed compiles (at different points), etc.
FWIW, I use an alias to display CPU, SBr, and HDD temps
alias sc='sensors | grep Temp: && /usr/sbin/hddtemp /dev/hd[ab]'
tom $ sc
CPU Temp: +46�C (low = +35�C, high = +55�C) sensor =
thermistor
M/B Temp: +40�C (low = +20�C, high = +45�C) sensor =
thermistor
/dev/hda: Maxtor 6Y080L0: 62�C
/dev/hdb: MAXTOR 6L040J2: 38�C
