Okay I've made some progress. After editing /usr/share/X11/xorg.conf.d/50-wacom.conf
Changed MatchDevicePath "/dev/input/event*"
to
MatchDevicePath "/dev/input/wacom"
Code:
Section "InputClass"
Identifier "Wacom class"
MatchProduct "Wacom|WACOM|Hanwang|PTK-540WL|ISD-V4"
MatchDevicePath "/dev/input/wacom"
Driver "wacom"
Option "Button2" "2"
Option "Button3" "3"
Option "PressureCurve" "50,0,100,50"
Option "Threshold" "60"
Option "KeepShape" "on"
EndSection
Now the wacom tablet responds to inputs! But, I don't have pressure sensitivity. 
I welcome any helpful input.
