OK, an update: I have now found a workaround in that setting desktop->peripherals->touchpad->tap_to_click to true in gconf-editor, tap-to-click and tap-to-drag start working just fine. But now the Mouse preferences panel still does not affect that check mark... turning 'Enable mouse clicks with touchpad' in that preferences panel has no effect whatsoever.

I'm updating the bug name to reflect that...
