Right now, i'm putting a huge load on the system, disk i/o, swapping high, virusscan, number crushing with ssh-keygen moduli etc ... 5 hours passed with this load and no single crash/freeze/lockup happened ! Normally with all this load sooner or later something would have happened. What did i do ? I disabled bttv support in the kernel, so no tv for me at this moment. I'm planning to let this run for at least another 5 hours with heavy load and see if still nothing happens... Keeping you informed.
