Indeed!  It should be possible to detect from the dmesg whether it's a 
trackpad and do that masking step.  My dmesg is:
ams0 at adb0 addr 3: EMP trackpad <tpad> 2-button, 400 dpi
wsmouse0 at ams0 mux 0

In any case, yes, your hack does indeed fix my trackpad to make it 
usable.  I filed a PR so it doesn't get lost port-macppc/28366

You might take a look at http://www.gnufoo.org/ucontrol/ which is a 
MacOS X replacement driver for the trackpad that supports these 
features.  There's also the shareware SideTrack (much better).  I 
believe the trackpad features of both packages were written by 
support@ragingmenace.com.
