The problem is that Xsun searches for the frame buffers from a list, as well
as /dev/fb.  With the IPC, the file /dev/fb and /dev/bwtwo0 exist.  One hack
would be to remove one or the other of these nodes.

There was also another problem where Xsun would not support multiple
frame buffers, so in the process of fixing that, I fixed the /dev/fb problem.

I would like to send this change to someone official so that it makes it
into the rest of the world.  Can anybody tell me who where, and how I
should send this fix?
