730 chipset
964 chipset
* Possible other SiS chipsets ?

Module Parameters
-----------------
================== =====================================================
force = [1|0] Forcibly enable the SIS630. DANGEROUS!
This can be interesting for chipsets not named
above to check if it works for you chipset,
but DANGEROUS!
high_clock = [1|0] Forcibly set Host Master Clock to 56KHz (default,
what your BIOS use). DANGEROUS! This should be a bit
faster, but freeze some systems (i.e. my Laptop).
SIS630/730 chip only.
================== =====================================================
Description
-----------
This SMBus only driver is known to work on motherboards with the above
named chipsets.
If you see something like this::
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 630 Host (rev 31)
00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
or like this::
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 730 Host (rev 02)
00:01.0 ISA bridge: Silicon Integrated Systems [SiS] 85C503/5513
or like this::
00:00.0 Host bridge: Silicon Integrated Systems [SiS] 760/M760 Host (rev 02)
00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS964 [MuTIOL Media IO]
LPC Controller (rev 36)
in your ``lspci`` output , then this driver is for your chipset.
Thank You
