 Thanks for the heads-up!  I think the declance hack should go away.  It 
should have gone long ago, but ISTR there used to be a problem with making 
such a large contiguous physical memory allocation in the modular case.  
Maybe it's not anymore these days.  I'll look into it when I get a chance 
to poke at hardware, which I have no access to at the moment.
