hi ff and sorry for delay
well the things are .. bad with glxgears
0,5 fps is the average

as you can see 3D apps are not working
same case for compiz (all kde desktop icons are gone and only the wallpaper is showed on display if i try to enable compiz)
tryed some options passed to i915 module, via modprobe.conf, with same bad results
anyway i use this computer as a server so all i need for my graphic card is to show icons, which are showed well if Option "shadow" "true" is specified in xorg.conf
so, in a way, this topic is closed but a new one will be opened

p.s
intel 810 and later in pcc works well and the same as specifying i915 in modprobe.preload, as i wrote before
thx again !
