I have a hp dv7-3065 laptop, and the touch controls need enabling. The volume mute and volume touch slide no longer work, but they did in 2010 beta. The wifi touch does work to turn off the wifi, but you must go through the wifi setup to enable it again.
This also has an infrared remote multimedia control, but not sure if that is a windows only thing.
I thought there was something in the 2010kde synaptic that enabled them, but here in Gnome, the synaptic keytouch doesn't help.
