I have the following config for a vlan interface:
DEVICE=eth0.6
BOOTPROTO=none
ONBOOT=yes
TYPE=Ethernet
VLAN=yes
BRIDGE=vlanbr6

and a bridge:
DEVICE=vlanbr6
BOOTPROTO=none
ONBOOT=yes
TYPE=Bridge
STP=off
NM_CONTROLLED=no

On Centos 5.6 this works as expected. On Centos 5.7 this also works but 
also outputs "RTNETLINK answers: No such device".

It seems the script is not broken but the code path executed is now very 
different (due to the missing "exec" call in the script). As a result the 
script at the end does a "ip route replace" on the bridge which apparently 
doesn't work. In the old version this code also exists but never gets run 
because the execution of "ifup-eth" ends with the "exec" line.
