Kernel panic during boot from Chameleon USB stick

I used the guide described here: aserebln.blog spot.com/ to create my own USB stick to boot retail SnowLeopard suited to the laptops hardware. I created my very own DSDT and everything, but everytime I try to boot from the stick I got a kernel panic.

Please have a look at the attached pictures.

My hardware is:
Intel Core2Duo
4096 DDR2 RAM
Nvidia 9400M G
Barebone Asus mainboard
MBR Partitioning (OSInstall.mpkg and OSInstall replaced)

Strange is, when I use the ready build Empire EFI ISO burned to a CD, I can boot without problems. So my laptop seems to be able to run macosx, but of course I want to use my own DSDT etc.

It would be really great if someone could explain what I have to do with the USB stick to boot from it. I have access to Windows, Ubuntu and a running SnowLeopard.

Thanks,
