I found a single edge razor blade in a paint scraper handle and shaved off
just a little bit of the jacket.  And now it works!

So I've learned my lesson that just because the HDMI appears to work under
OFW, it won't necessarily work under Linux.  And that the HDMI connector on
the B1 board really, truly is set in there weird even if it seems like an
unaltered adaptor appears to fit at first.

Thanks for all the help.  And thanks to Daniel Drake for fixing this in the
new build.
