As I already told you HAL don't do anything with or for wacom devices. Check 
the HAL upstream git repo! Everything you need to setup Xorg device should go 
into the related driver package.

And btw. IMO it's a stupid idea at all to do X configuration in HAL. Xorg 
should have it own config store or config backend where all the options get 
stored/handled. Especially calibration data (which is never generic and isn't 
stored statically in HAL, you have to set it again and again after each 
startup or for each new X session) or e.g. Wacom devices (which have 2, 3 or 
more X device sections for a input device) are an example why X should handle 
this itself (it can ask HAL for info about the hardware, but please not 
more).

Since the settings and parameters can differ between the drivers the driver 
should contains everything that's needed (incl. callouts, scripts, fdi, ... 
whatever).
