Sounds like a perfect target as a secondary arch. there is no reason why we cant support the older hardware as a community based effort of those interested in it. the primary arches are never going to satisfy everyone's itch but we leave the door open to do it through initiatives like secondary arches. The hardest part and the thing thats slowed things down so far is bootstrapping a new arch. its much much simpler for a x86 based arch as there is a baseline already bootstrapped. Dennis
