I previously had a near-perfect 10.5 install on my laptop, and after not using for awhile, I decided to try and install Lion. Install went okay, everything works except Onboard Graphics. I know how to fix the graphics using a DSDT patch, but the system freezes at random and I haven't been able to dump the DSDT since it crashes ~2-3 minutes after system boot. No kernel panic, no error message, the display just completely freezes and I have to hold the power button until it turns off. Does anyone here have ideas as to what might be causing this?
