Same question.

No, it isn't.  I changed nothing about the machine or kernel configuration
except for building with options UVM.  The securelevel is -1.

Besides, did you notice in the first part of my message that with the XF86_S3
server, I was losing using /dev/vga?  That's actually a friend's machine, so
I haven't had a lot of time to hack at it.

Yeah, it is.  But it's not because of the securelevel.

I still want to know why XFree is using 0xf9000000 as the third argument of
the open() it tries to do that mmap from, but that seems like an unrelated
bug.
