Okay, I made some adjustments and now the real culprit seems to be 
showing its ugly head but I am not sure how to deal with it.

Here is the relevant lines from /xorg.conf/:

*Section "Monitor"
Identifier "Monitor0"
VendorName "Polaroid"
ModelName "FLM-2632"
Option "NoDDC"
HorizSync 31.5 - 50.0
VertRefresh 25.0 - 65.0
ModeLine "1366x768" 65.00 1366 1048 1184 1300 768 771 777 806 -hsync -vsync
EndSection

Section "Device"
Identifier "Videocard0"
Driver "sis"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1366x768" "1024x768" "800x600" "640x480"
EndSubSection
EndSection*

...and here is the response to it in the /Xorg.0.log/:

* (II) SIS(0): Not using mode "1366x768" (illegal horizontal timings)
*
Now, the funny part about it is that I can go into /xvidtune/ and 
manually set it to the very same settings and the display goes into the 
proper mode just fine (of course /Xorg/ resets it when you log out). 
*This means that /Xorg/ is WRONG! *Now, how do I force /Xorg/ to accept 
the proposed display setting?
