For workaround, you can try to either: 1 (blind) press esc to get out of boot menu, then enter: vbe on; another option is to add hw.vga.textmode=“0” to loader.conf.

[I got to this sooner than I originally expected.]
With the patch applied, hw.vga.textmode="1" finally displayed
correctly for the ThreadRipper 1950X context that I had originally
reported. (The only amd64 FreeBSD context that I've access to.)
Thanks,
