Here's a blog entry from someone who managed to (in the true linux way of patching patching patching) got what he saw as stable NCQ support for his servers: http://blog.kovyrin.net/2006/08/11/turn-on-ncq-on-ich-linux/ It'd be nifty to see something like this pop up in FreeBSD 6.x for the Intel ICH7 boards.
