This is majority of AML part of it:
http://git.kernel.org/?p=virt/kvm/pcbios.git;a=blob;f=acpi-ssdt.dsl;h=d998867d70b6384c1f40356b9dd8a06b78b59022;hb=master

Seabios should be changed to allocate MADT table from memory that will
be marked as ACPI NVS in e820 and it should pass MADT table address into
AML code somehow (BOCH bios put it at address 0x0514 and AML read it
from there).

Note also that currently seabios created this SSDT dynamically and thus
can support any number of vcpus, by porting those changes we will limit
it to 15 vpus.
