Does that mean that I should give up on VT?  (If so, I feel rather cheated -- I bought the computer specifically for use with VT under XEN, and if it doesn't work, I've wasted a whole lot of money!)

You could replace it with a Q965 motherboard. Probably not as expensive as replacing the whole system. 
In general, how do you KNOW if your system is VT-capable?  If it doesn't seem to work, how do you know it's the chipset causing the problem?  And how will I make a better informed choice, if I have to buy a different system to replace this expensive paperweight!

The only clear way I've discovered to check for VT is by knowing both the processor and motherboard support it.

For the 965 motherboards, I've checked:

The only chipset that explicitly says it supports VT is the Q965/963.In fact these seem to be the only chipsets that explicit state they support VT. Maybe an Intel person can confirm this.

Even with the AM2 case, I'm not completely clear if ALL AM2 chipsets support AMD-V. It seems to be the case as there is no information to the contra. However the only thing I can promise is HVM works with my NForce 590SLI gigabyte motherboard.
