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 
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.
