http://www.openbsd.org/beagle.html says "Networking is working on the PandaBoard and the BeagleBone." Does that mean that networking also works on BeagleBone Black?
Also, there is a "ommmc(4)" link to http://www.openbsd.org/cgi-bin/man.cgi?query=ommmmc&sektion=4&arch=beagle that doesn't work: the link specifies "arch=beagle", but "beagle" is not among hte archs in the Architecture scrolldown menu.
