If you can get either to work individually when both are in the
machine, but they don't work simultaneously... assuming that
not loading the GLX module doesn't make things better, it sounds
like a bug in the S3 driver. I think I recall there being problems
at one time about it not setting its RAC flags correctly and
subsequently not being able to work in multihead configurations
correctly. That might be fixed in XFree86 4.3.
If the S3 card doesn't work alone when the NVIDIA card is
in the machine, that probably due to the S3 driver not being
able to work on secondary cards. Changing which card boots
via the motherboard bios can often fix that.
