This would not use the S3 X server but X4.1 which don't support S3
cards. You have to specifiy XSERVER = XF86_S3.

As Jim pointed out, if the client runs out of RAM the Xserver would be
killed and you would see some xdm error. However 16 Mb RAM should
probably suffice a bit more. Another quit test would be to choose the
"fail-safe" session from the gdm greeter (i.e. only one xterm)? If the
client doesn't handle that, then the problem is probably not the RAM.

As always, you can start in runlevel 3 and execute /tmp/start_ws. Then
you can see the error message from X.
