Kernel panic with iPC OSx86 10.5.6 Universal Final

I get this kernel panic immediately after DVD is booting, I don't even reach the installer.
This screenshot was taken from VMWare, but I've also tried to install it directly on my PC - same results.
MD5 of the iPC OSx86 10.5.6 Universal Final disk is okay.

Intel E6700, ASUS P5Q Pro, 4GB G.Skill (2x2048MB) 1066mhz DDR2

What can I do?

Thanks.
