Just Installed on TheKraven's CM7.2 with no problems and it is running fine, if anyone is having trouble getting it to work try Allow Write To /system and Allow Remount With dev/exec options under setup and If trouble booting make sure you know the name of the chroot launcher script (Changeable under setup)
Edit: If you still have problems get an app on the market called Debian Installer and download the files and it comes with lxde and vnc pre-installed to the image all you have to do is get it to boot just read the instructions on the app, there is also a Ubuntu Installer app but I couldn't get it to boot
