This machine has 1 GB of RAM, so it's not an issue. I've increased apreture size to 128MB, no effect (predictable, long shot). I've checked /var/log/messages, nvidia0 kernel module detects "GeForce Ti200" allright.
pkg_info shows compat5x installed, there's compat5x_enable="YES" entry in rc.conf. I don't think that Opera would work if the layer wasn't active. However, there's no trace of compat5x in system boot. "Local package initialization" result is empty. If memory serves me right, it listed it here on 5.4?

This guy says that you don't need compat5x to get it done. And curiosity -> i don't have glxinfo utility anymore. I'm checking via xdpyinfo and looking for extensions (besides, apps like tuxracer won't work without GLX). Glxinfo is part of MESA port? Hmm...i didn't have MESA installed on my 5.4, yet i had glxinfo.
