debug.acpi.avoid, how do i use it to tell acpi to not control the keyboard?

[John L.Utz III]

Hello again;

to quote man acpi:


     It is also possible to avoid portions of the ACPI namespace which may be
     causing problems, by listing the full path of the root of the region to
     be avoided in the kernel environment variable debug.acpi.avoid.  The
     object and all of its children will be ignored during the bus/children
     scan of the namespace.  The ACPI CA code will still know about the
     avoided region.

so, if i wanted to let acpi drive the power button and the suspend keypress but ignore everything else, how would one do that?

or failing that, can someone provide a sample use of acpi.debug.avoid that i can work from?

tnx!
