Here is how i did it, and it was EXTREMELY easy. Please note i dont have chameleon on my HD installed yet...im using a boot132/chameleon Cd to boot for now. I installed snow leop first, guid, and during install launched disk utility and made another partition as FAT32. (You can even resize and make another part. after os x install). Then i installed windows 7, which listed the drive and asked me to format it to NTFS, which i obliged. Thats it.
