NetworkManager is utterly useless for server grade work, such as pair bonding and bridges. It may be helpful for wireless management or modem connections, but I find it safer to to rip it *out* on CentOS 4 and CentOS 5, and urge turning it off by whatever means are feasible for RHEL 6 or CentOS 6 when it comes out.
Turning it off on CentOS 6 and current versions of Fedora is accomplished by the same means it always has been:
chkconfig NetworkManager off chkconfig network on
Unfortunately, this is not sufficiently reliable. Some idiot may re-run it, and from some bitter experience, I don't trust the system-config-network to behave well. NetworkManager is awkward to rip out of RHEL 6. (Not modular enough: too many tools that don't actually need it have RPM dependencies on it, so it winds up re-installed anyway.)
The key to *keeping* it off in RHEL 6, and I assume in CentOS 6, is the setting NM_CONTROLLED="no" in the /etc/sysconfig/network-scripts/ifcfg-* files. This is a new setting in RHEL 6, and I'm having difficulty finding documentation for it, but it seems to work in keeping NetworkManager's greedy little paws off my stable settings.
