It works. Here is the Xorg log file. Switching to console with
CTRL+ALT+F1 etc still doesn't work however. See the top pf the file for
loading of the driver and the bottom (probably) for switching to console
and back:
  http://pastebin.com/VA7dVBjL

Using Option "UseTiming1366" "true" in the Device section still causes
screen to remain black. the log file for that is:
  http://pastebin.com/7t2XWRpQ

Attached are the patches for my current version.

I have tried to contact the author via
https://gitorious.org/xf86-video-sis671/sis-671-fix but I have not yet
received any response. In his log file I see some syncing with Xorg so
(in response of Alan's message of the 12th of May, the author might be
interested to contribute this to Xorg. I have send him a message again
if he can help out with a this.

What can be done next to get :
- console working
- acceleration support
- driver shipped with Xorg
- other improvements (fix compiler warnings, UseTiming1366, etc.)

Pander
