Will dimmer switches dim LEDs?

If I replace halogen bulbs with LED clusters, will my dimmer switches still work?

Our house has a collection of halogen light fittings which look very cool but which seem to use a lot of power as well as loosing a lot as heat.
I'd like to replace these bulbs with LED replacement sets that replace a single halogen with a cluster of white LEDs. They tend to run on standard 230v mains lighting circuits, so I assume they have some sort of circuitry inside to back it down to a handful of volts.
The question is, how will these interact with the dimmer switches already on the circuit? Will the LEDs dim like the halogens do, or will the just shut off, or is the transformer like circuitry likely to stabilize the voltage to 5v regardless of the incoming voltage?
