Almudena, I think you are a little confused between userspace and gnumach. Translators run in userspace. I believe the kernel is standalone and if you need access to ACPI in there, you need to include ACPI code in gnumach directly. I have a feeling we are going to need all of acpica incorporated into gnumach eventually, because you need a full ACPI parser for learning the PCI interrupts and proper shutdown mechanism. If it were me, I would figure out a minimal way to add acpica to gnumach and write a header that can provide basic api access to the internals, and then build up the necessary code. Samuel might have comments on my ideas above. Damien
