Well it depends. I can see three modes of operation, one is the upgrade
card has all the logic in place to take over and disable the onboard 601
and boot the system built into it.

The second would be it has to have some nvram patches to let the above
happen

Third would be that the system boots with the 601 and then has an
extension or control panel that facilitates the switchover to the G3.

The first or second would probably work for us, unfortunately, due to the
nature of the upgrade, are pretty unlikely to be the case (let alone the
fact that nobody has actually successfully booted a 7200 yet).

Can you jack into it with a serial console and get the results of the dev
/ ls and .properties and words on any available cpu and l2 cache entries
in the device tree?

The nice thing about Windows is - It does not just crash, it displays a
dialog box and lets you press 'OK' first.
