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:-

So the vconfig command did something, but not enought.
You may need to load that 8021q module. Check with "lsmod". If it's
not there, try "modprobe 8021q".

More work to do...
