Hi Evgeniy, The invalid opcode error looks similar to the one in http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=404885. The guy is using the vesa driver. You might want to test with the vesa driver instead of i810 and see whether the same problem occurs (but you won't have accelerated 3D with vesa). If it still occurs, we'll have to reassign this bug to the server core instead of the i810 driver.
About the i810 driver, it has been largely reworked since version 1.7. It is now superseded with the Intel driver 2.0 (xserver-xorg-video-intel). Its first release had multiple problems on your i855, but most of them are now fixed in the latest git snapshot of the driver. So, if you want to test it, you have to install xserver-xorg-core 1.3 (currently in testing) and xserver-xorg-video-intel 2:2.0.0-5 currently in experimental. All this will require to upgrade several packages such as the libc6. Also, since your attached file suggests that you might have been trying multiple heads in the past, you have to know that mode detection has been greatly improved in the new Xserver 1.3 and intel driver 2.0. Most of the stuff in xorg.conf to manage resolutions, modes and multiple heads is useless nowadays. You might want to look at section #6 and #7 of http://wiki.debian.org/XStrikeForce/ReleaseNotes to change your xorg.conf accordingly. Let me know if you need more help.
