Please back this out.  FYI, there are two keyboard related problems 
with these Compaq/HP (Compal OEM) laptops.  The hint flag fixes 
infamous 'shutdown while probing keyboard' problem.  The second 
problem is resource conflict when ACPI is enabled.  The symptom is 
atkbd probe failure.  This problem can be fixed via ASL patch.  This 
can be done via network or with a USB keyboard.
