I've got colour IBMgraphics working on OpenBSD i386 on the console. I'm
thinking of writing up a mini nethack/IBMgraphics/unix/console howto, but
if anyone wants to get it working sooner let me know.

It may or may not work on non-i386 platforms. (WSDISPLAYIO_USEFONT ioctl
must be supported by the video driver.)

note: you'll have to patch your kernel or install current CVS to get it
working in OpenBSD on an 80x25 console. Yes, that's correct: thanks to
nethack, I found an OpenBSD kernel bug
