[K12OSN] which XSERVER for riva128?

[Petre Scheie <petre maltzen net>]

I've got a client workstation that can't seem to start its X server. 
When X tries to start, it fails but  reports that the machine has a 
RIVA128 chip but it can't seem to start the X server (I forget the 
actual error message).  I'm suprised that the XFree 4 drivers won't 
work.  In any event, I can hardcode the X server for this workstation. 
Does anyone know which one I should use for the RIVA128?
