Now you mention it, I have seen some other operating system use a reference to 'large' (4MB) pages.
I have heard some comments, though, about one of the Solaris versions not being able to use shared page tables (ISM) when the SGA goes over a critical limit - but this could be highly version-dependent, relate to some inability to use large pages with ISM, or half a dozen other things.
