Looks like I am going to have to ask on the Fedora-arm list:

vconfig add eth0 16
WARNING:  Could not open /proc/net/vlan/config.  Maybe you need to load 
the 8021q module, or maybe you are not using PROCFS??
Added VLAN with VID == 16 to IF -:eth0:-

ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN
     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
     inet 127.0.0.1/8 scope host lo
     inet6 ::1/128 scope host
        valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UNKNOWN qlen 1000
     link/ether 02:c4:03:82:c1:53 brd ff:ff:ff:ff:ff:ff
     inet6 fe80::c4:3ff:fe82:c153/64 scope link
        valid_lft forever preferred_lft forever
4: eth0.16 at eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc 
noqueue state UP
     link/ether 02:c4:03:82:c1:53 brd ff:ff:ff:ff:ff:ff

        valid_lft forever preferred_lft forever

ifup eth0.16
Error: Timeout 90 sec expired.

So the vconfig command did something, but not enought.

More work to do...
