I get no system messages related to the freeze...When the whole system freezes I cant do anything because it is no longer responsive to anything. I tried many option in xorg.conf (enable/disable agpmode=4,disable fastwrite) but the result was the same(I feel the system more stable without fastwrite but I dont think it's related).

Created attachment 11575 [details] xorg.conf (SAFE)

Could you try with Option "BusType" "PCI"? Your SiS AGP bridge might not work too well. And get rid of the Fast Writes option. I've yet to see a system where this doesn't result in instant hard lockup upon X server start (unless your bridge doesn't support it anyway, in which case the option gets ignored...)
Yes,I'm trying "BusType" "PCI" (for 3 days) and I dont experienced freezes. So we can say that the problem is Sis-agp host bridge... And now there is an hope to fix it (we could move this bug to video/agp)?
I am not sure it is limited to SiS. There are similar problems with intel and via chipsets, using ati and savage cards. These can of course be different bugs, but in general AGP and DRI seem flaky together. https://bugs.launchpad.net/bugs/117875 (ati on sis) https://bugs.launchpad.net/bugs/36596 (ati on intel) https://launchpad.net/bugs/33617 (savage on intel) In particular after suspend: http://bugs.freedesktop.org/show_bug.cgi?id=10761 (mga) http://bugs.freedesktop.org/show_bug.cgi?id=7417 (ati) http://bugs.freedesktop.org/show_bug.cgi?id=4607 (savage) (There might be more of these bugs for other cards, it's just that I get to know savage and ati issues since I have these cards myself).
