I hadn't thought about making it temporary - though I wasn't planning on
documenting it in the xorg.conf man page since users shouldn't be using
it except when told by a developer it's needed to workaround a particular
bug.   At this point, we're likely to get the fixes needed in Solaris
kernel/libraries for OpenSolaris & future Solaris releases, but not backport
to older Solaris releases, so we'll probably need to leave it in as a
configure option as long as Xorg supports building on Solaris 10, which is
likely to be many more years.   (I just dropped Solaris 7 and older about
a month ago, and from the bug reports I think Solaris 8 still has a build
error, but it's been a few years since I tried building that myself.
Solaris 10 is our current supported enterprise release though.)
