[LinuxBIOS] about make LinuxBIOS 64bit for Opteron

I hate that in LinuxBIOS (CAR and RAM stage) I can not access the range
above 4G, esp the last 4G in 1T Range.

I could use fs base to access that, but that is quite slow...

I fully agree. We should make a feature freeze and only let changes in
that fix something until we _verified_ that all (K8) mainboards are
working and on the same level (ie. equal cmos layouts, dual core, car
enabled, etc pp.)

One step at a time. We just recovered.

Besides that, 64bit is a must, no doubt.
