There's an initial implementation of acpi, but it's not yet ready.
Getting boot-time MP info is not enough, the information regarding
bus/interrupt entries is provided in many cases by AML methods.

So, in short, you need all of acpi to get that information.
The good news is that it's implemented.
The bad news is that is does not work yet.
What remains to be done is to supply bus information to the kernel
correctly, and that's not happening as of today.
