He isn't proposing a workaround, he's proposing disabling PCH for
OpenBSD, by creating host-openbsd.c.  If OpenBSD ever develops a
workaround, then that will require a host-openbsd.c file in any case.
So his patch will already have the right place to put that workaround.

In any case, I would take the opposite point of view.  Eventually, PCH
will need to support systems for which there is no fixed address
available (e.g., the Amiga).  When that support is available, OpenBSD
can take advantage of it.
