   	I do not think it is fair to force a new user to cross-compile
   	just to test out NetBSD.
   
   	Are there any sun4m boxes with less than 8M contiguous memory?
   	The lowest spec sun4m would probably be the classic which requires
   	at a minimum a pair of 4MB simms.

are these 2 simms mapped contiguously?  i dunno :)
   
   	Maybe have a SUN4C_SMALL with your changes and compiled with -Os?
   	(I'd prefer to see KTRACE added, but I expect everyone will have
   	their preferred set of options :)

sounds like a good idea for the older h/w.
