The radeon BIOS actually contains a table to tell us what chip is on
the bus,
in the KMS driver we read this table and load the appropriate hwmon
device,

There could possibly be other things on this bus than hw monitor
devices.

Though radeonfb should be considered mostly dead. 

I want to test that on a few powermacs first. "probing" i2c can be
destructive and f* knows what Apple put on those busses on some
machines.

If this is a concern to you, I'd be fine excluding CONFIG_PPC from the
change. Or are you worried about Intel Mac machines too? If there's an
easy way to spot all powermac machines, we can use that too, just let
me know how.

Haven't had a chance to look much yet.

Ben, any progress on this?
