There are actually two similar options, one is -nographic, which simply shows the serial terminal, and the other is -display curses, which will show the VGA text mode console on the terminal.

I suspect that for my purposes both of them will be useful. Thank you! I should go back and read the QEMU man page; groff -man -Tpdf <(gzip -dc /usr/share/man/man1/qemu-system.1.gz) generates a PDF of only 68 pages.
With this, I wasn't seeing any output with -display curses. It does work with -nographic or using a vnc connection to qemu's display, as well as on the two physical machines I currently have access to.

That would probably be because it is using UEFI text mode rather than VGA text mode.
Oh, I didn't know UEFI text mode didn't use VGA text mode! That could be an important consideration. But I suppose you can still frob the VGA registers to set VGA text mode, right? Even if you boot under UEFI?

While that way work on some hardware, on a lot of hardware it won't.
