Hum, I wonder if that explains my experiences with NetBSD. I was perfectly happy with NetBSD on my SE/30 and Q950. But when I tried in on a Q660AV, I found it mind-bogglingly slow. Until now, I always assumed that it was due to the X server trying to deal with a higher resolution display at a much greater colour depth (I used the X server on the SE/30, but only used serial consoles on the Q950). Or maybe I was just using a slightly newer version of NetBSD (I moved from 1.3 to 1.4 at some point). But if there is poorly supported hardware in there, that may be a better explaination.
