After a few tweaks I got it booting and everything went great! After using it for a bit I have found that the stock LiveCD kernel that it boots from doesn't have all the drivers I use. I have tried just simply replacing the default kernel with the kernel from my system and  it didn't work. I have done some research and I recompiled my kernel to include devmapper. But it still gives a kernel sync error problem, it seems to not be able to find the CD after detecting all the devices. Is there something I'm missing? Or is this even supported in the LiveCD mailing list?

Yeah, you're missing the initramfs and the init scripts that tell the 
kernel to continue loading the system from the CD, not from a partition 
as it would usually do.

I can't recall off-hand if Alex wrote anything about how to include the 
initramfs into a custom kernel. For starters, look through the README on 
the CD.
