Bug#546741: xserver-xorg-video-sis: X fails to start (SiS 771/671 - No devices detected)

sources are available here:
http://www.linuxconsulting.ro/xorg-drivers/
and here:
http://ncc-1701a.homelinux.net/~linux-sis/index.php?page=Downloads

also it is possible to use precompiled unofficial ubuntu packages with 'sis671' or 'sisimedia'  driver with xserver-xorg-core from current debian testing. 
I think these drivers are based on the same sources
