Yes, I think a BX would be a good choice.

We'll probably have to change some of the framework a little
to make aquiring resources more dynamic.

I'm not sure on a good interface yet, until I get a chance to
look more at PCI.  Though, if you lay out what kinds of things
you need in the framework of bochs, I'll add them.  Sounds
like you have a good idea of a clean interface + options
in .bochsrc.
