   I had never used the aperture driver, but instead had the securelevel
initialized to -1 in sys/kern/kern_sysctl.c. A change must have caused
that file to be updated and undo my change. Perhaps a (oh no, not another)
kernel config option might help? Simple enough to implement, I should
think. I can see that there might be reasonable arguments for making
the level of kernel security optional. Or just include the aperture
driver in the tree. If anyone is going to be putting things into the
kernel, it should be the NetBSD team, not XFree86, and having device
drivers as standard equipment makes for good PR.
