There is no fdi-file for wacom devices in HAL. And it wouldn't make any sense 
to add it to HAL since there is the linuxwacom package which should contains 
it as in your case evtouch should deliver a fdi-file (if this is what the 
package maintainer wants).

Please add such FDI files to the related packages which already contains the 
needed driver. It makes no sense to have these files in HAL, especially since 
you need also the special driver (for X or/and the kernel). The package that 
contains the driver should also install the (may) needed fdi-files.

It would be the same as we already do with e.g. libgphoto or libmtp.
