If you experience video/audio stuttering and/or periodic crashes of different software with EXC_I386_DIV (divide by zero) errors in __gettimeofday() after wakeup, the following might help you.
The original VoodooTSCSync only syncs CPUs once, on system startup. It's not enough for my T60p, which is out of sync on every wakeup. I modified VoodooTSCSync to sync on every power-on event. You can find my patches and a precompiled binary at http://code.google.com/p/voodootscsync/ ... etail?id=1.
Enjoy,
Bgm.
