ha!  I got it to work.  Had to be done manually, I have no idea why the ifcfg- scripts just won't take it, all it ever accepted was eth0:0 as a regular subinterface and thats it. 


ip link add link eth0 name eth0.1 type vlan id 1
ip addr add 0.0.0.0 dev eth0.1
ip link set eth0.1 up

dhclient eth0.1


# ip -d link show eth0.1
3: eth0.1@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default qlen 1000
    link/ether b8:27:eb:20:25:16 brd ff:ff:ff:ff:ff:ff promiscuity 0
    vlan protocol 802.1Q id 1 <REORDER_HDR> addrgenmode eui64 numtxqueues 1 numrxqueues 1

# ip addr show eth0.1
3: eth0.1@eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default qlen 1000
    link/ether b8:27:eb:20:25:16 brd ff:ff:ff:ff:ff:ff
    inet 192.168.0.117/24 brd 192.168.0.255 scope global dynamic eth0.1
       valid_lft 86066sec preferred_lft 86066sec
    inet6 fe80::ba27:ebff:fe20:2516/64 scope link
       valid_lft forever preferred_lft forever



And... no one else on here knew that...

hmm, so then why won't normal subinterfaces work either then?  Just taking a look over the code, I see what looks like vlan support as well:

         /* Init Rx */
         /* Set Vlan */
         ret = smsc95xx_write_reg(dev, VLAN1, (u32)ETH_P_8021Q);
         if (ret < 0)
                 return ret;

I don't believe the smsc95xx driver supports vlans (from a grep of the
driver code) I'm not sure if that's a hardware limitation or whether
it's just not been implemented in the driver.
