I've had a similar problem with my Radeon 7500 - for some reason the 
XFree driver for it does a divide by zero if I give it my monitor's real 
scan rates, so I have to run a lower scan rate. I conjecture that the 
scan rate is right on the edge of where the monitor will change its 
internal settings, so once in a while the scan rate glitches over, and 
the monitor resyncs. I'm not sure it is a purely Netscape issue, I think 
it just happens when "lots of stuff" gets drawn to the card.

Have you tried changing what rez you are running with ALT-CTRL-KP- to 
see if the problem goes away at a different scan rate?
