The SVGA server VGA Wonder driver in V3.1 is broken and requires a patch; 
as I understand it this has been fixed in V3.1.1.  It won't work at all 
no matter what your configuration values are set to.  I too beat my head 
against the wall until some kind soul (I forget his name, but I can look 
it up. :{)

The patch to fix this is:

*** 3.1-ati_driver.c    Tue Sep 27 09:06:18 1994
--- ati_driver.c        Thu Nov 17 11:10:33 1994

          /*
           * Set up extended register addressing.
           */
-         outw(0x03CE, ((ATIExtReg & 0x00FF) << 8) | 0x0050);
-         outw(0x03CE,  (ATIExtReg & 0x0300)       | 0x8051);
          ATI_IOPorts[0] = ATIExtReg;
          ATI_IOPorts[1] = ATIExtReg + 1;
  
--- 1197,1202 ----

You need to apply this to the ATI driver in the directory 
"/usr/X11R6/lib/Server/drivers/vga256/ati", then rebuild the SVGA 
server.  After I did that I was able to use the configs from my V2.1 
system as well as the configuration program.

Thanks,

Mike
