Without tweaking in the hdaps.c, the insmod + force=1 leads to:

hdaps: supported laptop not found!
hdaps: driver init failed (ret=-6)!
hdaps: initial latch check bad (0x04).
hdaps: init failed!
input: hdaps as /class/input/input5
hdaps: driver successfully loaded.

None of the /sys entries are usable: "Device or resource busy"
So I guess I've to tweak around with the patches (very badly placed inline) 
from the hdaps-devel list.

Thanks,
