Subject: Completely reworked ACPI tables

I'm too exhausted right now, but I rediscovered the memory mapping issue
of my ACPI implementatio and need to fix it ASAP. Otherwise I won't be
able to use any ACPI table without causing a page fault. I have no clue
why exactly this is happening and the internet says that I shouldn't
need to memory map them. Well, I'll look into it later.
