please help, os x 10.5 won't start, with kernel panic

Happy for my macbook pro for almost two years. Laterly it's been unstable and freezes sometimes. Two days ago it went to kernal panic and shows kernal panic screen and asks for restart everytime it restarts.

It won't start on DVD or safe mode (it just hangs there and keeps spinning). For single user mode, it first worked and I was able to remove login items, but it froze again and now generates the following panic log.

All the hardware have been the same and I have installed vpn a few months ago and dropbox last week...Please help! Appreciate it.

Thanks a lot for replying. The problem still exists and is getting worse. I used to be able to do a CD boot and hardware test and then boot normally again. Hardware test complained about video controller. Now I can't even boot. Here's the panic report. Thanks a lot for helping...
