I just upgraded my notebook to karmic. Enabling tap to click works now (gnome-settings-daemon 2.28.0-0ubuntu2), but it is still disabled by default. I'm usally not at all for changing default settings just because they don't fit my personal preferences, but in this case I'd suggest reverting this to the pre-karmic behaviour - tap to click should be enabled by default.
