Yes xset q gives

[...]
DPMS (Energy Star):
   Standby: 600    Suspend: 600    Off: 600
   DPMS is Enabled
   Monitor is On

I found out that if I disable the console framebuffer from the parameter 
of grub.cfg

# Uncomment to allow the kernel use the same resolution used by grub
GRUB_GFXPAYLOAD_LINUX=keep

then the DPMS in xorg start working (but is very annoying because I use 
the console and with something like 80x25 it's become very nasty).
