Yep, it seems like the MMIO aperture for the video card might overlap the
ethernet controller memory resource (depending on the size of that memory

It should never hang in that case though. And I thought the initial PCI
resource allocation takes care of resolving overlaps?

Can you boot some other way (i.e. no BootX)?
