I have no hardware capable of running LinuxBIOS (except a few OLPC
machines with Geode GX, but they use a different CAR setup).
Besides that, testing this code in v3 is rather difficult because no
machine uses it (yet). Testing this code in v2 requires a few
adaptations, depending on whether you test K8 or generic x86.

So, no, sorry, that code change has not been tested at all.

Marc: The AMD Family 10h BKDG says CAR should be set up with a size of
exactly 48k. Is that a SHOULD in the RFC sense or just a suggestion?
