first post!! lol, well, here's the thing, i have one msi wind with arch linux, with the coming of xorg 7.4, xorg-server 1.6, and the new intel drivers, my nightmare begins, crashes, unresponsiveness, and a lot of things, so im planning a reinstall, it'll be an old arch linux and i was thinking to not upgrade xorg and the related packages, but in the meanwhile i was reading a lot about freebsd and im really really interested in trying it, so i want to know, if possible, i can install the 6.4 RELEASE iso, and then upgrade to 7.2 RELEASE without upgrading the xorg,xorg-xserver,mesa,intel driver, and all the related packages so i can stay STABLE for real 
thankyou in advance!
