Some people apparently use a vga-splitter cable and a framegrabber card on a 2nd pc (e.g. to take BIOS or POST screenshots). The results are slick. If you have the required hardware, that is.
Then there's the analog route: Digital Camera > Display, but not very elegant.
Other than hooking up a serial cable and redirecting console output, are there any software solutions that work in OpenBSD?
I mean sth. like the Linux-centric fbdump (which grabs the Linux framebuffer device) or snapscreenshot (requires Linux /dev/vcs*).
