	While that would be possible (and probably no bad idea just for the cosmetic
	value) I wonder why that hardcoded entry is there at all - in an U5/U10 in
	default configuration the on-board hme would show up as hme0 anyway if that
	entry would simply be deleted, or am I missing something?

The problem is that simba's are wired so the first bus is
used for PCI slots and the second bus is used for on-board
devices.  Our PCI code probes buses in order, so the 
PCI slots are probed before the on-board devices.

The real solution to the problem would be to change
our PCI probe code to use the PROM device tree rather
than PCI config space to probe devices.  That would
also solve our interrupt remapping problem, and
resolve the need to scan the device tree multiple
times to hunt for specific devices.
