Snow Leopard won't boot.

[Nindijin]

So hey guys. I had (still have) a working Leopard install (10.5.8) that I obtained through iDeneb. Thought it was time to try my hand at upgrading to Snow Leopard, so I installed it on a partition of my Leopard machine. Everything went reasonably smoothly, until I tried booting into it. It gets stuck while loading Darwin/x86. I booted using verbose mode, and this is what I got:

Loading Darwin/x86
Loading kernel mach_kernel
Loading HFS+ file: [mach_kernel] from 42346f0
Loading HFS+ file: [mach_kernel] from 42346f0

And that's where it freezes. Can anyone help me out? Anything would be greatly appreciated. Thanks in advance. (Using Chameleon 2 RC4, if it makes any difference).
