Ok - can you build with ACPI debugging, set /proc/acpi/debug_level and 
debug_layer to 0xffff, hit one of the keys, turn the debugging back off 
and then send me the log? Easiest is to do something like:

echo 0xffff >/proc/acpi/debug_level; echo 0xffff 
>/proc/acpi/debug_layer; sleep 3; echo 0 blah blah

so you don't have to try to disable them while stuff's appearing all 
over your screen. There'll be a lot of output, so if you could send it 
to me rather than the list then that would be great.
