Best way to get max KVA setting?

I could probably grep for this, but what's the best way to get a hold of
the # of pages (or MB of ram) that max KVA is set to?  I'm adding another
autosize option, and I want to base it on min (KVA, ram) so that it
doesn't balloon on boxes where ram >> KVA.

Thanks,
