Hi Darcsis,
yes it has a lot to do with the 64bit nVidia driver
that patch I'm trying to get reviewed implements one of the features requested by nVidia
note that there are only two missing features left ... and this is one of them ... in other words this one could potentially leave us with only one missing features
check this out: http://wiki.freebsd.org/NvidiaFeatureRequests

regards,
mgp
