Machine is a Dell Optiplex GX260, with an 845G video adapter. With xorg-x11 6.8.0 and up (i was using 6.7.0-r1 with no probs) I can not use a color depth of anything greater than 15. Anything higher, xorg seems to "freeze" and I get a white square where the mouse pointer is and I must do a hard reboot. It doesn't seem to be affected by screen resolution, as I can do 1600x1200x15bit just fine, but can not do 640x480x16 or anything higher. X does seem to "start" and I get a mouse pointer and can move it around, but before it shows my gnome splash screen it locks up. It does it for all users, regardless of desktop environment. Reproducible: Always Steps to Reproduce: 1. Set DefaultDepth to 16 in /etc/X11/xorg.conf 2. run startx Actual Results: Locks up with a white square where the mouse pointer is. Expected Results: Start xorg-x11 :P

Is http://freedesktop.org/bugzilla/show_bug.cgi?id=1817 your bug?
I dont think so, I dont get snow, I get a white "box" where the cursor is. The freedesktop.org bug report isn't in-depth enough for me to tell. The vga adapter isn't the same either, if that's where the bug is, although I can't remember now which driver the f.d.o bug reporter was using.
Could you quickly search bugs.freedesktop.org for i810, i830 or i845 in summary and see whether any of those are yours? Also, by the mtrr overlap I'd guess you're using some sort of framebuffer console. Try turning that off and see whether it works around things.

I've had the same problems on a Dell Inspiron 1100 with i845G, little white square and all. Work-around: update to gentoo-dev-sources 2.6.9-r6 configure with CONFIG_DRM_I915 instead of CONFIG_DRM_I830 Seems to solve problem.
Got the same with i810. turned off dri and glx in xorg.conf and it worked. sad but true.
Josef, what kernel driver are you using, and what X version?
Have any of you had this fixed in recent updates?
Let me know if the latest versions of X (including modular) fix this problem. There is an even newer i810 driver available, but it won't work without some other newer components.
