The responses I have seen to this problem in this list and the fedora-test 
list summarize as follows:

1) the *CURRENT* NM does not do a (non DHCP) static configuration very well or 
at all, but they are working on it for a future version, and occasionally DHCP 
and NM are fun.

2) if your computer does not roam and/or does not use wireless networks, then 
do the following UNTIL the static network version of NM is ready:

service NetworkManager stop
/sbin/chkconfig NetworkManager off
/sbin/chkconfig network on
service network start
system-config-network #configure as you
#                 # always have in the past.
reboot #if you're feeling frogy.

3) the biggest unfortunate thing about the above is that it may or may not be 
possible to configure a kickstart postscript to do 2 while installing on a 
mess of machines in an automated way.
