The fix for the intel X driver is here:
http://gitweb.freedesktop.org/?p=xorg/driver/xf86-video-
intel.git;a=commit;h=4f5500abe209b92b39ae1f2d7a1118362ac95034
But Mesa/DRI also needs to be fixed accordingly. See the following response by
Keith Packard:

Yeah, but you'll be limited to 4096 pixels -- Mesa can't go beyond that.
Here's what I tried:
diff --git a/src/mesa/drivers/dri/i965/brw_context.c

I suspect the 3DTextureLevels and CubeTextureLevels need frobbing as
well, but I didn't try to figure out what the right values might be.
