Applied Nathan Yawn's (natey@hcis.net) patch to add a driver for the BayRAD
display. The patch applied cleanly, and compiled properly. At least, "it worked for me." :) I don't have such a display, thus I cannot test that the driver actually works, but it at least doesn't do nasty things or break the compile. Thanks, Nathan!
