Recent posts, of course, suggest that I am wrong and that it applies (for the obvious reasons) to all X servers. However, I have still not tried it :-). I am not sure how BSDI manages the securelevel + X thing. Perhaps they provide a kernel driver for the requisite video card interface, which can on demand provide the i/o port access and memory mapping, but only in such a way that the video card can be accessed. Alternatively, they hacked around it and there are holes in their securelevel implementation. I don't have desktop access to any BSDI machines right now, but once I return to the US, I'll give it a try.
