Now granted I have not spent too much time working with 10.6 on a hack but I don't think I have ever come across this flag. I have seen arch=x86_64 & arch=i386 which forces 64bit & 32bit respectively.

Just curous, when you boot using these flags are you running in 64bit mode? Now I know on my iMac when I boot into 64bit I can type uname -a in terminal I get x86_64 at the end of the string while I get i386 if Im running in 32bit.
