Not sure whether to put this in the 00-05 or the 06+ section, but here it goes:
With no regard to physical size and fitment into the dash, is an 00-05 Cluster compatible with an/the 06+ Databus revisions?
Random question: Are the clusters considered a node on the network or are they kind of dummy and just running like in a promiscuous mode? In other words, are they specifically addressed or do they just listen?
I don't know the ins and outs of the Class 2 Databus, but I will tell you that I'm pretty sure it's a node as you can pull OBDII codes out of it (along with the radio) and test all the functions in it with a Tech 2 (needle sweeps, lights, transmission gear indicator, etc).

The cluster is (as all modules are) an active node. The cluster requests info across the OBD-II bus to drive the gauges/. Like Frank points out, it can also accept commands to do things (like sweep gauges, turn on MIL, illuminate indicators, etc)
The 00-05 cluster is Class2 and the 06+ is CAN and they are not compatible
Beyond that, there are tons of architectural difference that make them incompatible as well, not to mention the physical sizes are different
