XFree86 version 4 errors

[Pollywog <croak@shadypond.com>]

I have been using the svga server (xserver-svga) and I just installed
xserver-xfree86 (xserver-xfree86_4.0.1-5_i386.deb) in order to try it out.

The error log is lengthy, so I am posting  just the last part.

(II) LoadModule: "mouse"
(II) Loading /usr/X11R6/lib/modules/input/mouse_drv.o
(II) Module mouse: vendor="The XFree86 Project"
	compiled for 4.0.1e, module version = 1.0.0
	Module class: XFree86 XInput Driver
	ABI class: XFree86 XInput driver, version 0.1
(II) I128: driver for Number Nine I128 chipsets: i128, i128v2, i128t2r,
	i128t2r4
(II) Primary Device is: PCI 00:10:0
(EE) No devices detected.

Fatal server error:
no screens found

What does this mean, exactly?  What am I missing?  I went back to the svga
server until I can figure this out.  I am using the documentation at:

http://sxs.sandbox.dynip.com/stepbystep.htm  but I still don't see what I
am doing wrong.

thanks
