mostly got rid of a bunch of old #if'd out IRIX stuff, which I guess I'd 

left there so I could remember how to do stuff when I finally did the
IRIX port...  which I've now done, so no need to have it here (not that
there was previously anyway, thanks to CVS).  Also made things do
getload() once before clear_screen, so that in case getload() gives a
fatal error (as is the case on IRIX if ttyload can't read /dev/kmem, at
least with the current implimentation), the user can actually see it.
