PATCH: x11-drivers/xf86-input-synaptics & sysutils/hal

It's always bugged me how I can't seem to get Xorg to associate 
xf86-input-synaptics with my synaptics touchpad on my FreeBSD laptops.  
These patches appear to work.

  * sysutils/hal: hal currently declares /dev/psm0 to be an 
"input.mouse" always; I added code to test for the presence of sysctl 
hw.psm.synaptics.margin_top and, if found, declare the device to be an 
"input.touchpad" instead.
  * x11-drivers/xf86-input-synaptics: There is no AutoDevProbe() method 
in the SynapticsProtocolOperations struct; I added a naive one which 
returns TRUE iff the InputInfoPtr name is "PS/2 Mouse" and the char 
device path starts with "/dev/psm".

I have the following ports and their dependencies installed for test 
(WITHOUT_NEW_XORG=yes in /etc/make.conf):
  * sysutils/hal
  * x11/xf86-input-mouse
  * x11/xf86-input-synaptics

Tested the following scenarios:
  * /etc/rc.conf: moused_enable="YES" added, and commented out
  * /boot/loader.conf: hw.psm.synaptics_support="1" added, and commented out

X server appears to DTRT in each scenario, but I don't seem to have the 
use of my touchpad scroll area without psm(4) synaptics support turned on.

Comments/suggestions welcome, including the proper mailing list/people 
to send this to and how to get this committed.

...and yes, I know Xorg is dumping sysutils/hal :-)
