I don't exactly get what you want to achieve. Especially, I don't get
the link between VLAN support and IP/MAC changing... Maybe you can be
more specific.

By the way, Linux supports 802.1q VLAN encapsulation. This means you can
connect a Linux box to a VLAN aware switch using a 802.1q trunk to one
of its interfaces, say eth0. Then you can add logical interfaces to each
VLAN carried by your trunk, sau eth0.1, eth0.2, etc. (naming can be
changed to vlan1, vlan2, or more, you have 4 different naming schemes,
see documentation).

Once your logicial interfaces are created, you can see regular trafic
through them, 801.2q traffic being seen through native interface (eth0).
Then you only have to provide routing and filtering between your
interfaces and you're done.

If you feel brave, you can use interface bonding to provide your trunk
additionnal bandwidth or high availibility feature.
