  | Patch:

Sorry, that didn't get applied as I intended, I  should have sent a diff,
not just words...

Try the following patch instead, this applies to the original file,
and includes Martin's patch, as modified the way I intended you to
modify it.

No guarantee that this will make anything work, but it might supply
some more info.

You can use this with, or without, the acpi config of the pckbc
(which seems to make no difference) - or both ways...
