Here's the read_resources code from qemu after my latest patch. Is this what people are thinking? Notice that I explicitly allocate VGA space

I think I like this. It makes sense to me. The legacy VGA space nadd the legacy IO space should be reserved in the southbridge as you have done.
I actually think I just bumped up the base in the northbridge this time around.
All right. If I do this then I can't ignore fixed resources in the allocation algorithm anymore. It still works right now because 0-0xfff is the largest resource, so it gets allocated first. I think it would break if you tried to allocate an IO resource larger than that.
Do we want to take fixed resources into account in the allocator?
Thanks, Myles
