I've had a running system with iPC OSx86 incl. patches 1 and 2

Yesterday I made a fresh installation with iPC OSx86 10.5.6. with patches PPF 1, 2 and 3. After reboot my system can't get past the moment after my account has been uploaded using my Apple ID and password. It looks like een problem with the kernel or ethernet, but I installed the same kernel and ethernet driver as before on my working system.

The system us able to get my name, adress etc from the internet, but in the next step a bunch of letters scrolle down my screen. In teh background i can see the screen from OS.

Anyone an idea what can be the problem?
