No, you have to add the ServerFlags-section yourself, see man xorg.conf.

Copy the file provided by the driver from 
/usr/shale/hal/fdi/policy/20thirdparty/ and edit as you like. Note that 
for joysticks you just need to run 'lshal' and attach that to a bug 
report. The driver doesn't ship an fdi file yet, but it will be fixed 
soon, and the more coverage we get for various devices the better.

No and no.

should work if evdev doesn't grab the device.

No, the fdi method is enough.
