Thanks to the great efforts of Morgan Tsai of SiS we support the SiS966
southbridge now:
From: Morgan Tsai <my_tsai@sis.com>
It supports SiS761GX / SiS966 chipset, only for AMD K8 platform so far.
Due to integrated VGA sharing system memory, some code in southbridge
folder have to init northbridge.
