It looks like those are the default settings for the synaptics Xorg driver (xf86-input-synaptics upstream or xserver-xorg-input-synaptics in Ubuntu). In the latest version of xf86-input-synaptics (1.50), src/synaptics.c contains the following lines:
pars->tap_time = xf86SetIntOption(opts, "MaxTapTime", 180);
and
pars->fast_taps = xf86SetBoolOption(opts, "FastTaps", FALSE);
which as said before, seem to be the culprit of this problem. A simple patch to change those values in the source code would fix this problem.
