well it seems chameleon can not handel 4k offsets... chameleon problem 129... i got around it by installing it to efi partition but its a pain sometimes as lion wants to "fix" my efi partition if i do a disk repair on the root disk. the simplest methode i found was to use chameleon wizard and activate efi support in it's preferences. then once activated mount it to check version then format to hfs from the efi menu then install to it bye selecting the efi partition... your theme has to be there too in efi partition or it will be in verbose so you have to mont it go to finder and drop in the theme folder, and modules folder and make sure the boot file is in there in the efi root... in the wizards preferances un check hide boot file.
