I use gentoo and the latest version of xorg won't start.
I reported it to the gentoo bugzilla and was told to report it here.
The link to the original bug report (well, the intresting message) is
http://bugs.gentoo.org/show_bug.cgi?id=132277#c4

It's a Pentium D 850, running in 64 bit mode, using gcc 4.1.1 (but IIRC
when I first reported the error I was running 3.4).
Kernel at the moment is stock 2.6.18-rc2, but the same happens with
2.6.17 (again, maybe when I reported it was 2.6.16, it's been a long time).

I don't have any fancy CFLAGS or anything like that. More system information
is listed in the gentoo bug.


Here's a brief review:

I've got an Intel 945G video card, which uses i810 driver.
If I try to upgrade xorg from xorg-server 1.0.2-r7 and xf86-video-i810
1.4.1.3 to 1.1.1 or 1.6.0, it won't start, showing the following:

[...]
(II) I810(0): Activating tiled memory for the back buffer.
(II) I810(0): Activating tiled memory for the depth buffer.
(II) I810(0): [drm] Registers = 0x50100000
(II) I810(0): [drm] ring buffer = 0x40000000

Please let me know if you need any further information or testing.

Thanks a lot,
