Why assume it's a different bug? I would almost wonder if it might affect 
all Sandy Bridge GPUs. In any case, I no longer have the original 
motherboard (it was recalled, as I said in the first post), nor even the 
revision of it (it had other issues that weren't being fixed). I *assume* I 
will have the same problem with my new motherboard (Intel DQ67SW), but I 
haven't verified that yet. I'll be sure to try a netconsole when I have to 
reboot next and get a chance to try the most recent 2.6.38 and .39 kernels, 
but at the moment it seems reasonable to address the problem bisected in the 
bug, even if it turns out to be different.
