I tried GeForce3 (and all other nvidia cards I had at the time)
on Linux before the 4.2.0 release. Everything worked fine. I've
tried all my cards since then at various times after I've made changes
in CVS. 4.2.0 should work fine with that card.

-configure frequently doesn't work, even under Linux. It seems to
break periodically. All it takes is for one of the drivers to do
something wrong.
To me it looks like there are problems in core XFree86 code (int10
maybe) dealing with your system. You said you have XFree86 source?
Have you tried building from source. At least then you could build
a debug X-server and find out where it crashes.
Can you telnet into the machine and start XFree86 under a debugger?
Run "gdb XFree86" and from the gdb prompt type "run". When it
crashes type "bt" to get a backtrace. The symbols that aren't
visible resolvable (have ?? for names) can be printed by calling
LoaderPrintSymbol. eg:
(gdb) call LoaderPrintSymbol (0x08587f48)
I don't think you can do this on a core dump but only on a running
X-server. Even if you haven't build with debug symbols this may
still produce useful trace information. The previous trace you
did on the core dump had too many ?? in important places that you
can't resolve unless you have the special XFree86 loader version of
gdb or XFree86 was started under the debugger and you call
LoaderPrintSymbol.
Mark.
