Yes, so can I, and VGA out comes back to life once UEFI loads. Also, 
unce UEFI loads, the remote network console via the Java client starts 
to work, too.

Disappointingly, the fact that u-boot seems to arbitrarily decide to 
stop using local console, does seem to make it's usefulness rather 
diminished as the first stage boot-loader. :-(

But yay, I have it working! :)

Now to put Tianocore files onto the UEFI partition...
