For the love of god, can we please rename "bits X" in the
struct bdb_general_features? That caused me endless pain. It should be
"byte 0"
Also, I guess there is a problem when the VBT is missing, and we have a
dont have a CRT on non-ULT (since the default seems to be true). This
however is no worse than the current situation AFAICT.
