Yes, I also get that oops but other than that, both link order versions 
you sent out work -- ie, booting with acpi=noirq gets me to a functional 
system with the quirk having run for PNP0c02 (acpi=off disables all of 
PNP0c02) and doing its job.

For some reason only some of your messages seem to be making it into my 
inbox (in order, at least) but either of these that is:

http://lkml.org/lkml/2008/9/30/242
http://lkml.org/lkml/2008/9/30/261

With the attached on top, all's working fine for me.

Rene.
