Issue with DRI after latest update

[xtremyst inxtremo]

I used WITH_NEW_XORG and rebuild xorg-server and its dependencies,
uninstalled xf86-video-ati and build xf86-video-ati-ums but X failed to
start, I tried again with
Section "DRI"
    Mode 066
EndSection
in my xorg.conf in order to make it work. I got X-server to start but the
resolution was much lower (1280*1024 from 1920*1280 that i normally have).
I also tried to watch a video on mplayer with xv as video output driver but
I couldn't watch the video. It's pretty much the same thing, it acts as if
DRI is disabled.

PS: When I have KMS disabled and startx fails I have two options, reset
again and again until I get it to start or I can disable DRI from xorg.conf
and then the issue goes away but cant use xv anymore. What i don't
understand is why having DRI enabled makes startx sometimes fail and other
times work without me making any changes. If you're interested you can read
about this weird behavior on this FreeBSD forum post i started a few months
