There is also invalid values with i386 RC1 GENERIC. But when I  
disable most devices the message disappears.
If I add just the network cntrlr (IRQ 11, device 18) or the usb  
cntrlr (IRQ 11&5, device 16) it reappears.
I also have the display cntrlr on IRQ 11, bus 1. It might be there.  
We could need more memory for something...
I don't know ACPI code and internals.
