Just a caveat to the GigaStack comment from Milan. You CAN configure a cascaded GigaStack link as a Trunk (ISL or dot1q); it doesn't have to be point-to-point. The only downside is the Cascaded connection will only work in half-duplex (like a hub) so as the traffic increases so do collisions and the useable throughput. This is not applicable on point-to-point Full-Duplex links as collisions don't occur here.
In response to your question on whether we have tested VLAN Trunking Over a Cascaded GigaStack link - Yes, I have deployed a few networks where this type of topology is used. Ideally there would be no stacks at all (stacking sucks) but where cost is an issue, needs must.
With the newer switches (2970 & 3570?) Cisco have taken a different approach and used a proprietary stacking port so all the Issues with the Stack Port being Ethernet should (hopefully) be eliminated.
