Just to add my own input and a few other things:
I've done two of the things suggested here that appear to have solved
this problem for me. I don't know if either of them alone would have
done it, since I made both changes at once. Basically, I upped my
"Virtual" size to 2048 2048, and I applied Albert Damen's debdiff patch.
Prior to making these changes, I suffered from the same X freezes that
others have described: no CTRL+ALT+F1 to switch to a TTY, no
responsiveness in X to mouse clicks or keyboard input (except for
ALT+SysRq+REISUB and ALT+SysRq+K, the latter of which killed at least
part of the X session but left me with an unreadable screen), but
ability to move the mouse pointer. I appear to suffer from no such
problems now (so far, anyway, after hours of usage under the same
conditions which typically would've caused the freezing by now). I can
view the panorama image provided above, and so on.
Here's the relevant portion of 'lspci -vvnn' and 'apt-show-versions -a
-p xserver-xorg-video-intel' (I've attached my xorg.conf for reference
as well):

Incidentally, I previously saw (and posted on) a bug apparently similar
(if not identical to) this one at:
