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

Hi,
v2 and v3 have almost identical CAR setup code with identical bugs for
CAR sizes != {4k,8k,16k}. In v3, the erroneous code paths are not

trigger these bugs, resulting in holes and/or smaller size of the CAR area.
