Unabashed shame on me ! Why take the simpler, most obvious path, when you can 
waste bandwidth and bother everybody at xorg ?! Thank you so much, Dimitar.  
I'm so ashamed I hadn't done this before. It works !

I've been living with 800x600 for almost a year, and a partial-screen 1024x768 
for only one day, thanks to you. Strangely, Knoppix auto-detection scripts 
created the correct modelines, but Debian didn't. Would it be the case of 
filing a bug against the X server package in Debian ?

Thanks your patience
Paulo
