There's no such thing as a standard PC.  There of unique hardware out 
there and it's even worse because a lot of hardware is only meant to be 
accessed by the BIOS.

So I don't think any OS should have a problem with vmport other than 
knowing what it is, and expecting certain things from it that we may not 
be providing.  I don't see this as being any different than any other 
device emulation.  When we find this, we should extend vmport to include 
these features.

However, I don't think we should write new guest code that uses the 
vmport interface, because it's not an interface we have any control over.
