configuring X problem

[BadMan <badman718@pop3.smartworld.net>]

I use Debian2.1 , installation went fine everything works fine, EXCEPT I
just cant get Xwindows to work.
I have  16Mb Diamond Viper TNT AGP Video Card (Version 1.95E5802),
IntelliMouse 1.1A PS/2 Compatible.

I try to configure XFree86, write the new configuration, when I try to
start
X, the screen blinks as if it was trying to start X and then goes back
to
virtual console with the following error message:

System: '/usr/X11R6/lib/X11/xkb/xkbcomp -w
1 -R/usr/X11R6/lib/X11/xkb -xkm -m us -em1 "The XKEYBOARD keymap
compiler
(xkbcomp)
reports: " -emp" >" -elm "Errors from xkbcomp are not fatal to X server"
keymap/xfree86 compiled/xfree86.xkm'

Fatal server error:
    Cannot open mouse(Operation not supported by device)

X conection to: 0.0 broken (explicit kill or server shutdown).

What am I doing wrong ? I've tried selecting different mouse and
keyboard
options, but still get the same error.
Thnks in advance !
