Change port for sshd and mysqld?

Question

The default installed mysql and ssh do not respect the port settings in their config files (/etc/my.cnf and /etc/sshd_config) respectively. For firewall reasons we have to run these on different ports.
It is not clear where both the services get their port settings from. I found a hint that sshd actually gets it from the /etc/services file:

I haven't yet tried that, but it seems possible, any experiences?
Mysqld sets the port on the commandline that runs the server, I found the setting in the /System/Library/LaunchDaemons/org.mysql.mysqld.plist file. I removed that setting (so that it respects the my.cnf setting) but unfortunately Server Admin seems to write over that file when it restarts the MySQL server. Does anyone know where Server Admin gets that setting from?
I guess I should add a note that says I'm annoyed that this is hard, but really I just want to get it working

Thanks, yes, I can confirm that editing /etc/services for sshd worked, now I have sshd listening on 22 and another chosen port.
Mysqld is still tricky. A temporary workaround is:
$sudo launchtl unload /System/Library/LaunchDaemons/org.mysql.mysqld.plist
then edit that file, removing the --port=3306 argument then load it again. When that line isn't there it does respect the settings in my.cnf. I'm pretty sure that this persists across reboots, too.
However if you stop and start MySQL with Server Admin.app that file is re-written, including the port line that you deleted. So you either have to do the above again, or remember to restart mysqld (hopefully doesn't happen often) by using launchtl unload or service mysqld stop. I'd love to get this working through the GUI.
