There's an easy way to determine in Windows if your trackpad is
emulating multitouch or providing real hardware multitouch on newer
laptops (running newer trackpad firmware): Open up your Mouse control
panel, then press shift+alt+i.  This will open a debug window.  From
there, go to the device0 tab, and look near the bottom for - and i might
have the name wrong here - Finger Sensing (#).  This value will show you
how many fingers the driver is reporting.  Now, watch this number while
you apply contact to the pad in several different ways.  First, touch
the pad with two fingers spaced a little bit apart.  Next, touch the pad
with 3 or 4 fingers spaced with as little space between them as
possible.  Next, try pressing the entire side of your finger to the pad
at once.  Does it show more than 1 contact point when you try the second
two methods?  If so, then the firmware is taking any wide-area contact
to the trackpad and assuming that the two edges of the contact area are
your two separate fingers, meaning that it is emulating multitouch

I would also note that, strangely, with the updates from a few nights
ago, the "spazz" behavior I was previously seeing when I would multi-
touch my trackpad has stopped.  Touching the trackpad with two fingers
now produces normal single-touch mousing behavior.
