OK, the sources were actually in xserver-xorg-video-intel (not xf86-).

Downloaded the sources with apt-get source ..., installed the whole bunch of
-dev packages needed.

Configured with xvmc, because that is how the package is installed on Ubuntu
Trusty:
./configure --enable-debug --enable-xvmc --prefix=/usr

Then:
make install DESTDIR=_dist

Then:
copy _dist/usr/lib files onto /usr/lib (saving the old ones first)
sudo reboot

>From another machine:
gdb Xorg $xorg_pid
(gdb) c
Continuing.

Now, enable full window resize and drag (I had those disabled to have a
somewhat useable desktop). Open a window, grab it and wiggle it around -
freeze!

Results:
- No output on the GDB console.
- Same or similar error messages in /var/log/syslog (I saved syslog and the new
crash dump, I can post them here if needed).
- after 30-40 seconds I get "*ERROR* context hanging too fast, declaring
banned!" in the system log and the GUI seems to come back to life, but not
really working.

Anyway, at least I have the sources compiling and I can take a stab at getting
familiar with them. I will also get the Linux kernel source and see if I can
add some printk()s to see on which exact commands from userland trigger the
errors. If you have any better ideas, let me know.
