Requiring the first byte of the EDID base block header to be 0 means we
don't fix up as many transfer errors as we could. Instead have the
callers specify whether it's meant to be block 0 or not, and
conditionally run header fixup based on that.

will look for exactly the r-b-ness mentioned in the mode code. This
