Sis Video/Xorg segfault in current

[J. Scott Heppler]

In an old ECS desknote with and Sis 630 video chipset
a segmentation fault occurs during X startup
OpenBSD 5.3 release ran fine.  It is an old laptop and Sis has not made
video cards for years so this is a low priority.

I am willing to test since the hardware is getting scarce.  If there is
not much interest, a comment to that effect would be helpful.

Hi,

Yes, the recent upgrade to X server 1.14.1 broke the SiS driver. This
is a know problem, and the X.Org people are aware of this:
http://lists.x.org/archives/xorg-devel/2013-May/036138.html

As soon as this effort produces a working driver again, we'll merge it
in OpenBSD.

In the mean time, if you could follow the instructions in
/usr/xenocara/README to build xserver and driver/xf86-video-sis with
debugging symbols (-g) and run X under gdb from a second machine to
get a backtrace when the server crashes, it will help a bit.
