ACPI/PCI-bus issue with compaq evo n160

[Fredrik Lindberg]

The solution suggested by Mauritz worked, the ACPI stuff works now. 
This is what I have in my loader.conf

debug.acpi.disable="lid pci_link"
hw.pci.allow_unsupported_io_range="1"
hw.cbb.start_memory="536870912"

I would like to thank everybody who have helped me troubleshoot this.

(please remove the NOSPAM stuff if you reply private)
