The cyapa.ko driver should be in /boot/kernel/cyapa.ko , at least it is
there in CURRENT; dont know if it was backported to 10.3;

I prepared a KNOPPIX 7.6.1 USB boot key (KNOPPIX is Debian based) and
can now see what Linux thinks/sees of the hardware. On my C720 where the
cyapa driver works fine it says in dmesg:


...

I will do the same in the evening with the C720 which was
changed/repaired by Acer... You should do something like this too, or
with OpenBSD.
