OK.

And the particular column contains white pixels? It could be entirely
black (i.e. in between the white characters). Try running linuxconf or
something else with a non-black background.

Yeah, the screen is of fixed resolution. And since lcd glows longer
than crt, it has a lower, usually fixed refresh, both horizontal and
vertical. So your XF86Config setting probably don't matter (off topic:
unless you explicitely exclude the required mode? then it wouldn't
work at all).
Can you set the graphical card on 800x600? If so:
- how does it look on the screen: centered, smaller? scaled to full-screen?
- are there still wrong pixels? Are they in the middle column?
How much graphical memory do you have, can you lower the (bit) depth
of the 1024x768 mode?
