I created some basic framework for dynamic ACPI table creation, but it
is by no means a complete ACPI implementation. Plan is to also support
powermanagement on AMD64 (and hopefully get ACPI going for other ports
as well)

Currently, no. Not all information is provided by LinuxBIOS yet to make 
this work. (Much of it can be generated from the device tree) 
The ACPI implementation currently only allows to utilize the HPET timer
in Linux (which is not possible without ACPI at all)
