Well, it really doesn't have anything to do with ADB. The problem is
actually the macio bus layer, but we don't have CONFIG_ options for
that. I've been working on getting the macio code running in 68k,
so I was thinking of introducing a CONFIG_MACIO. Would this be an
acceptable option? On 68k, I would just default it to yes if the
config has CONFIG_MAC, but it could be made a real question for ppc
since the platform stuff doesn't really let you select just a pci
powermac kernel anymore. Any comments?

I suppose if anyone still has one of those old CHRP machines, we
could probably get hydra supported by macio_asic to get some of the
other drivers working on it.
