well, you have to be careful. We've had more than one problem with
"common" code that was not so common. CAR is so tricky, and one
platform changes may break another platform in ways we don't expect.
CAR, in fact, scares me. It's fragile. I'm particularly concerned
about the idea of unifying via and amd code. The changes some
well-intentioned people made years ago to some via northbridge code to
"clean it up" -- it broke many things -- are still fresh in my mind.

I contribute very little code at this point, really zero in the last
year, so I don't believe my opinions should be taken that seriously
:-) I'm really more than anything recommending you all to be very
careful. Anything you do to CAR needs to be extensively tested.

So let's call it my .01, not my .02 :-)
