I've merged this for RHEL-5.2 (along with cset 492), and now have
multiple reports that it has fixed the X crashes --- thanks!

We'll need to keep it queued for pvops, too, as that is going to need
the whole PROT_NONE special handling in order to support migrate.  I'm
away all next week, I'll have to deal with it when I get back.

Cheers,
 Stephen
