Yepp. It does not do DSDT, since I created the APIC entries while the
system is running, by detecting the devices. The DSDT is compiled byte
code, so since we probably don't want to cope with creating it during
runtime, we will have to provide a much more complete hardware
description in Config.lb so we can create ASL source code.

And lots of things are hand crafted (Power Management tables). I bet
with a little more ACPI knowledge we can generate them from nice
looking, easily readable config files.

I'm not sure why we need IRQ overrides, it doesn't really seem to make a
difference in Linux. 


SRAT is not there either.. IIRC the problem was that the LinuxBIOS table
does not hold a description of which memory belongs to which CPU, but
rather linear chunks, which was why I didn't do it.
