And what is the resolution you need?

Ugh... "that" card :-(

This is the second time I see a report like yours: sis driver cannot go 
beyond 800x600 (it defaults to VESA) and it seems to be already reported 
(at least for Ubuntu):

[needs-packaging] no working driver for sis 671/771 video cards
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-sis/+bug/301958

Take a closer look into that bug and check if you are facing the same 
problem. Maybe you can also find some workaround in there :-?

Besides, there is a Debian bug that could also be of your interest:

xserver-xorg-video-sis: X fails to start (SiS 771/671 - No devices 
detected)
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=546741
