You start debugging the ACPI tables, and specifically in the context
of what Windows thinks of them.

You'll at a minimum need a checked build of Windows 7, some way to
communicate with WinDbg, and lots of time.

Another, complementary, approach is to compare with another data set.
So you would start Windows 7 using qemu without coreboot, see if that
works, and if so then study the ACPI differences between the two

It's pretty retarded that the Qemu folk refuse to contribute to
coreboot and insist on duplicating lots of code within SeaBIOS,
but there's not too much to do about that..
