Did that and it did work for a while, longer than the average with 3.5. I was already about to write a success report, but then it hung again yesterday. I'm not using this laptop very intensively, so, it is hard to collect statistics.
You could try to reproduce the error by writing a big file e.g.
dd if=/dev/zero of=deleteme bs=1M count=80000
or similar and watching high definition video on Youtube (1080p) or running a few instances of glxgears. That triggers a gpu hang in my case after just a couple of seconds.
In my case, the hang doesn't occur when using SNA (or a kernel < 3.7, which isn't the case with your bug). I have this in my xorg.conf:
Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "SNA" EndSection
Without this, every 3.7 kernel produces a gpu hang within max. 1 min.
