2 things: If you take the monitor apart, leave it to rest for a while before
going near it. A very high voltage builds up on there and it takes a while
to dissipate. If you touch the wrong part, you will blow yourself out of the
building!
Secondly, you have confused me with your last statement - "The monitor works
just fine... ... with new nvidia drivers for the video card seems to have
regained any lost sharpness". If this is true, then what problem remains?

I would suspect there is nothing sealing the two and that is
why dust eventually got in... but to know for sure you'd
have to start taking it apart. I caution you to first
Google for a safe method of discharging the tube, it will
hold a high voltage charge for awhile, though I don't know
how many days.
I suppose it could instead be that there was a seal like
foam and it just deteriorated over the years and this "dust"
you see is actually particles off the seal.
