Maybe evdev works better? I seems there is a problem when both absolute 
AND relative axes are exposed, but since you seems to have some control 
over the kernel module, you could simply suppress those. That should be 
enough get X recognize it as absolute.

I cc'ed the list so better ideas may emerge.
