I tested with each of the following "stanzas' in /boot/loader.conf,
using vt (vs. syscons) in each case (though that breaks video reset
on resume after suspend):

# hw.vga.textmode="0"
vbe_max_resolution=1280x800

This works, and provides a graphical console (depth 32).


hw.vga.textmode="0"
# vbe_max_resolution=1280x800

This also works, and provides a low-resolution (and depth 16)
graphical console (800x320 or something similar, IIRC).


# hw.vga.textmode="0"
# vbe_max_resolution=1280x800

(That is, not specifying anything for hw.vga.textmode or
vbe_max_resolution.)

This boots OK, but I see no kernel probe messages or single- to
multi-user mode messages.  I can use (e.g.) Ctl+Alt+F2 to switch to
vty1, see a "login: " prompt, and that (also) works.  (This is the
initial symptom I had reported.)


hw.vga.textmode="1"
# vbe_max_resolution=1280x800

This works -- boots OK, and I see kernel probe (&c.) messages; this is a
text console (mostly blue text; some white, against a dark background.
It's a medium-light blue, so it's easy enough to read (unlike a navy
blue, for example).
