FWIW, NetBSD/amd64 just runs on this box. I will check again whether it was with or without ACPI, but it seems to be running properly in 64-bit everything and doing SMP. I'm gonna see whether that's good enough for the person whose computer this will be; I don't think he has a significant preference between the systems, and if I can make that work, I'll do a few more experiments, send in data points, then load something else and ship it. :) -s
