But this page describes exactly how to setup it up using evdev. The only 
difference when using HAL is that evdev now auto-detects it (hopefully). 
So I really do not see how HAL by itself can change anything.

What of course could happen - distributions may run arbitrary scripts as 
part of HAL detection which may remap keys etc. Check with lshal if you 
have any of them; try to add FDI to turn all these scripts off for your 
device to see of it helps. If it works, this may need to be added to 
standard FDI set.
