[CentOS] Kickstart from tagged VLAN?

I've searched around but haven't found a definitive answer yet, is it possible to kickstart from a tagged VLAN? I found this bugzilla:

https://bugzilla.redhat.com/show_bug.cgi?id=431915

But I can't find out how far the vlan support goes. I haven't found anything about it in any kickstart docs.

I have two tagged vlans:

Vlan 100 - server subnet Vlan 101 - backup subnet

From start to finish anaconda needs to pick up a dynamic address from vlan 100. After that the kickstart file specifies the static adress from vlan100 and it's address from the backup subnet. Anyone know if this is currently possible? If so any nod in the right direction would be appreciated
