If it's a build time "SunOS emulation _or_ larger VM" then I would
definitely think GENERIC should switch to the larger VM by default. If
its a 'need to rework stuff and its too difficult to build both from

Does anyone know if all m68k platforms have the same limits? (Apart
from sun2, for obvious reasons :)
