Snow Leopard not booting after black screen

[KSwoosh]

Yesterday I was using OSX Snow Leopard (installed from the iAtkos S3 V2 dvd), and I've used it a few times before (I'm actually waiting for a new WiFi card to start using OSX more), without problems, but yesterday something weird happened:

I had my laptop and computer on, and had my laptop booted in OSX, I was about to install the VoodooBattery kext, but didn't get around to do it, so my laptop just stood there.

When I looked at it some minutes later, it suddenly had a black screen...

 

And now, it won't boot anymore... :S

 

When I boot in verbose mode, the only line that is displayed is this:

Loaded HFS+ file: [system/Library/CoreServices/SystemVersion/plist] 479 bytes from 435aec0.

after that, nothing else happens.

 

Booting in single user mode doesnt work either... (I actually have no clue what single user mode does, but i thought it was worth a try.)

 

Does anyone have a clue what could be causing this? And how I can fix it?
