any chameleon2 based loaders has panic isue when mkext and kext permission is incorrect.
but with right system cache chameleon 2 work's with 10.6 okey,so if you install via OSInstall.mpkg do repair permission and rebuild cache.
only PCEFIv9 can boot SL with wrong mkext or with -f.
sadly old chameleon 1.011 sources are unavailable.(
