Intel SNA - unable to disable vsynch

I'm using testing repo xorg-server and mesa and recompiled the testing xf86-video-intel so that it would have SNA support all in order to play HoN on my GMA 3100. The problem is that even though there's  a noticeable FPS boost, i can't seem to disable vsynch, which lowers it unnecessary. I have /etc/X11/xorg.conf.d/20-intel.conf containg:

 Section "Device"
    Identifier "Intel GMA 965"
    Driver "intel"
    Option "SwapbuffersWait"	 "False"
#    Option "AccelMethod"	"uxa"
 EndSection

I've also tried disabling vblank from driconf but it doesn't seem to have any effect whatsoever... Any ideas?

Oh, another thing: I my /var/log/Xorg.0.log there's a line:

[  9528.992] (WW) intel(0): Option "SwapbuffersWait" is not used

Try launching it like so:

vblank_mode=0 HoN # or whatever the executable is

Re: Intel SNA - unable to disable vsynch

I did and I'm not sure if it works... I get:

ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: default value of option vblank_mode overridden by environment.
ATTENTION: option value of option vblank_mode ignored.
ATTENTION: option value of option vblank_mode ignored.

Maybe it's incompatible with SNA?
