re: xsrc/50429: Xserver fails to start on Ultra-5 andNetBSD/sparc647.0

[matthew green <mrg%eterna.com.au@localhost>]

something related to kern.securelevel and this commit breaks X on my U10:

http://mail-index.netbsd.org/source-changes/2012/03/13/msg032767.html

before this commit, stuff works.  afterwards, if securelevel is set,
X fails to startup.  forcing securelevel to -1 also fixes -current
and most likely -7 too.

this diff is not small and touches a large number of files, but there
are only a handful that should be relevant here and most files are
other drivers.
