How to run a fastcgi application under root ?

Hi All,
 
I intend to run my fastcgi application (DataSystem.exe) under root perms.
So I first configured apache to add suexec wrapper using:
--enable-suexec
--with-suexec-caller=root
--with-suexec-userdir=/home/usr/cgi/usr
 
And I add next tokens to httpd.conf.
SuexecUserGroup root root
FastCgiWrapper On
FastCgiServer /home/usr/cgi/bin/DataSystem.exe -group root -user root 
 

My environment is:
Operating system: Linux Montavista 2.4.20
Apache version 2.0.55
Mod_fastcgi version 2.4.2
Platform is embedded system using IXP425 processor.
File system is Read Only.
 

The most prominent tokens in httpd.conf are:
 
SuexecUserGroup root root
ServerRoot "/usr/local/apache2"
User cgi-usr
Group users
LoadModule fastcgi_module modules/mod_fastcgi.so
FastCgiServer /home/usr/cgi/bin/DataSystem.exe -group root -user root
DocumentRoot "/home/usr/aweb/tree"
<Directory />
    Options FollowSymLinks
    AllowOverride None
    AuthType Basic
    AuthName "Please enter valid user and password"
    AuthUserFile passwd/passwords
    Require valid-user
</Directory>
<Directory "/home/usr/aweb/tree">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
UserDir /home/usr/cgi/usr
DirectoryIndex ComMainOffline.htm
ErrorLog /usr/local/apache2/logs/error_log
ScriptAlias /cgi-bin/ "/home/usr/cgi/bin/"
<Directory "/home/usr/cgi/bin">
    AllowOverride None
    Options +ExecCGI
    Order allow,deny
    Allow from all
    <IfModule mod_fastcgi.c>
    SetHandler fastcgi-script
</IfModule>
</Directory>
 

The users and rights for the related directories are:
 
# cd /home/usr/cgi/
# ls -al
drwxr-xr-x    1 cgi-usr  users          28 Jan  1  1970 bin
drwxrwxr--    2 cgi-usr  users          40 Jan  1  1970 usr
 
And cgi application 
 
# cd bin
# ls -al
-r-xr-xr-x    1 cgi-usr  users     2675305 Jan  1  1970 DataSystem.exe
 
 
 
Next error appears that when Apache starts:
 
[warn] module fastcgi_module is already loaded, skipping
[warn] (97)Address family not supported by protocol: FastCGI: there is no fastcgi wrapper set, user/group options are ignored
 
error apache Log file reports:
[notice] suEXEC mechanism enabled (wrapper:/usr/local/apache2/bin/suexec)
[warn] module fastcgi_module is already loaded, skipping
[notice] Apache/2.0.55 (Unix) mod_fastcgi/2.4.2 configured -- resuming normal operations
FastCGI: process manager initialized (pid 155)
[warn] FastCGI: server "/home/usr/cgi/bin/DataSystem.exe" started (pid 157)
 

But cgi application starts running in cgi-usr user instead of root I desired.
Apache always starts from root.
 
Here you are a process list from ps comman:
 
root       139  0.0  3.5  5320 2244 ?        S    11:23   0:00 /usr/local/apache2/bin/httpd -k start
 
cgi-usr    154  0.0  3.1  5108 2020 ?        S    11:23   0:00 /usr/local/apache2/bin/httpd -k start
 
cgi-usr    155  0.0  3.2  5108 2028 ?        S    11:23   0:00 /usr/local/apache2/bin/fcgi- -k start
 
cgi-usr    156  0.0  3.6 29904 2316 ?        S    11:23   0:00 /usr/local/apache2/bin/httpd -k start
 
cgi-usr    157  8.8  4.5 25532 2900 ?        S    11:23   1:02 /home/usr/cgi/bin/DataSystem.exe
 

I'm really stuck on all this configuration stuff.
All I need is run cgi application (DataSystem.exe) in root user.
I need do this because this application has to access others programs that only runs in root user (like ifconfig, start-stop daemonds ...)
Security for me is not a problem because it runs in a closed embedded system with no external users.
 
Please some help.
thanks
