Description of problem:
In Fedora 9 the middle button emulation (i.e. pressing left and right buttons
simultaneously) does not work with synaptics.
I have disabled the Touchpad and is only using the "pointing stick" (i.e
"GuestMouse"). As a test I enabled the Touchpad, and the middle button emulated
worked correctly with the two mousebuttons located next to the touch pad, but it
still did not work for the mouse buttons used for the pointing stick.
The middle button emulation has worked correctly in Fedora 7 and Fedora 8 on the
same hardware.

Hardware platform:
Dell Latitude D830

Version-Release number of selected component (if applicable):
synaptics-0.14.6-7.fc9.i386

How reproducible:
Always. 

Steps to Reproduce:
1. Use hardware with a touchpad/pointing stick combination with separate
mousebuttons for both point
2. Enable GuestMouse, set TouchpadOff to 1
3. Set EmulateMidButtonTime to a reasonable value (75)
4. Try pressing both mouse buttons simultaneously 
  
Actual results:
No middle button emulation

Expected results:
Middle button should be emulated
