Ok, by inspection (sorry, still dont have much time) - your kernel code
is sending to group 1; i.e

genlmsg_multicast(skb, 0, 1, GFP_ATOMIC);

you need to change that to send to your assigned id, i.e:
genlmsg_multicast(skb, 0, acpi_event_genl_family.id, GFP_ATOMIC);

then the user space code will work. I should be able to look at it if it
doesnt work by end of week.

cheers,
jamal
