/usr/lib/dockutils/dockhandler was executed with args "ibm/hotkey HKEY 
00000080 00001007".  It returned 1, which usually means something went 
wrong.  Programs return 0 when everything's worked properly.  So:  What 
does dockhandler do?  Does it write a logfile?

Yep, similar things here except the last arg is 00001002 not 00001007.

Is this thing a shell script or a binary?  I have 1 script in /etc/acpi 
that handles all ACPI events.  It splits $1 into $group/$action, and 
then has a lot of case/esac statements.  There's a default event that 
execs 'logger "ACPI group $group action $action is not defined" ', so 
events without cases get captured too.

Dunno.  Then again, I use radeontool, not /proc, to turn off the 
backlight on my T42p.
