hm, I don't like it when defaults change so dramatically!  So the 
problem wasn't evdev / hal related.  Why on earth would tap to click be 
turned off by default now?

Two finger scrolling was on, but "broken" on the new synaptic driver, as 
every time I scroll up, then lift my finger off, it scrolls down further 
than I can scroll up!

Even the acceleration had changed to make it unusable.  I've left the 
evdev mouse driver as a second mouse to catch all usb mice, and I have 
my touchpad as the default:

Section "InputDevice"
     Identifier     "Synaptic Touchpad"
     Driver         "synaptics"
     Option         "Device" "/dev/input/mouse0"
     Option         "SendCoreEvents" "true"
     Option         "Protocol" "auto-dev"

     # turn on finger tap:
     Option		"TapButton1" "1"       # Left button

     # don't use two finger scrolling:
     Option "VertTwoFingerScroll" "false"
     Option "HorizTwoFingerScroll" "false"

     # use edge scroll areas:
     Option "VertEdgeScroll" "true"
     Option "HorizEdgeScroll" "true"

     #continue scrolling when touchpad end reached
     Option "CornerCoasting" "true"
     Option "CoastingSpeed" "2"

     #set speed and accel:
     Option	    "MinSpeed" "0.20"
     Option	    "MaxSpeed" "0.60"
     Option	    "AccelFactor" "0.020"
EndSection

Note I only used TapButton1, not 2 and 3, as I want to double tap for a 
double click, not double tap for a midle/right click.

thanks for all the suggestions!
