Yes, NM_CONTROLLED=no works with ifcfg-rh plugin. I wouldn't call it 
deprecated, it's just one of the plugins and is meant to work with Red Hat 
distro config files.

Other plugins have its own "unmanaged" configuration.

Keyfile plugin uses "unmanaged-devices" option to list devices that should be 
unmanaged.
For older HAL-dependent NM, the above described example should work.
For new NM (without HAL), unmaneged-devices are specified by its hardware 
address. So use something like this:

[keyfile]
unmanaged-devices=mac:00:1e:65:30:d1:c4;mac:00:22:68:11:59:a1

(use lowercase in MAC)

Right.
HAL was used in 0.7. At present, NM uses udev and HAL dependency has been 
removed.
