I have a Multi-Gesture sticker on my 
	Acer Aspire 5741-333G32Mn Model No. NEW 70 + Win 7 Home Prem OA,
It looks to me ( speculating) from curved arrows as if for eg picture rotate ?
	(Maybe similar to dual finger shrink & expand/ zoom on some Mac)

I havent put BSD on my Acer just yet, so just the Win it came with.
  ( No idea what X support might be, but if by chance your MS-Win is deleted,
  I could try what my mouse does with Win, except I've no idea what MS
  software to try the mouse With, so would need someone to tell me that. )

I googled & found in German
  Summary: Writter downloaded a driver & it didnt zoom.

Pointed to page in English:
  Enable Multi-Touch Gesture (Finger Scroll, Momentum and ChiralMotion)
  on Synaptics TouchPad in Windows 7/Vista/XP/Server
  Synaptics TouchPad
  "for marketing reason, Synaptics official standard drivers for
  most Synaptics TouchPads does not support multi-touch Synaptics
  Gestures. Synaptics' drivers lock gesture features on all
  non-supported OEM notebooks and laptop PCs, except for certain
  gadgets such as ASUS EEE PC. So multi-touch is disabled even
  though touchpad hardware does support them."

(Sounds like most MS customers get their hardware
crippled by the driver unless they pay more )

For us I guess
	echo 'boot_verbose="yes"' >> /boot/loader.conf ; reboot ;
	dmesg | grep -i synaptics
	Then web search eg x-org for more synaptics driver info after ?
Good luck, (& I'll hope to hear what you may find please :-)
