Yep,

# lsmod | egrep "openvswitch_mod|brcompat_mod"
brcompat_mod            5713  0
openvswitch_mod        82997  2 brcompat_mod

# grep COMPAT /etc/sysconfig/openvswitch
BRCOMPAT=yes

# ps auxw | grep brcompat

The /sys/class/net/vbr314/bridge/ directory actually exists, despite the
error messages.  The content differs a bit from a standard bridge
configuration in Linux (it lacks some files):
server1# ls /sys/class/net/vbr314/bridge/ | sort >/tmp/vbr314.ovs
server2# ls /sys/class/net/vbr314/bridge/ | sort >/tmp/vbr314.bridge
# diff /tmp/vbr314.ovs /tmp/vbr314.bridge
