The modprobe lines can be dropped into /etc/modules-2.6.* file.

So you want to start/run a service at bootup. Starting services like apache or bind are done through the scripts contained in the /etc/init.d/ directory. To start apache:
/etc/init.d/apache start
To stop apache:
/etc/init.d/apache stop
Where "/etc/init.d/apache" is the execution of the script and "start" or "stop" is an argument passed to the script. If you need to create your own script, well the Debian developers have left us a skeleton script at /etc/init.d/skeleton. See:
http://www.debian.org/doc/FAQ/ch-cus...tombootscripts

This might seem like overkill but as a sysadmin I tend to do this the 'proper' way even if it is overkill.
