That is the whole point of this, yes. Furthermore, it is expected that we *also* would be able to set platform flags based on early probes.

Not entirely surprising, since this stuff is more or less randomly sprinkled through the existing code. We have a huge bunch of legacy code and yes, it needs cleanup.
This is a huge opportunity, of course, but it's going to be a lot of work. A lot of this is likely to overlap directly with the needs of Xen, too.
