First, VLT and 802.1q tagging are two different things. To my knowledge 
neither of the 3c59x Linux drivers (the one that comes with the kernel or 
the one from Scyld) offer support for VLT which is a 3Com proprietary 
scheme. The Scyld driver offers support for 802.1q tagging.
I have no idea about the support offered by 3Com's own 3c90x driver.

This can also be achieved at higher levels, with a packet-based firewall.
