Great, thank you for your effort here! I'm more than happy to test anything you
come up with and provide any feed back I can.

I actually haven't installed OSX on this machine in years. I assume it's in
high performance mode. I've actually been trying to switch over to the low
power GPU in my testing here with no success. So I'm not having too much
success with many of the workarounds & patches posted in this thread. Am I
correct in understanding that you think I should start another bug report with
this trace? Does that mean this bug report is only concerned with issues when
running from the 9400M then?
I'll keep trying to produce some more info relevant to this bug by working on
getting switched over to my 9400M.
Does anyone know if it's possible to switch from "9600M GT mode" to "9400M
mode" without using OSX? I've tried several of the mysterious outb grub
directives. "outb 0x750 0" turns my screen off (I assume that's shutting off
the 9600M GT) but I can't seem to enable/switch to the 9400M to get the screen
back on.
