Hi,
As far as I know the "-legacy" flag force Leopard to boot in 32 bits mode.
With mach_kernel 9.0.0 SSE2/SSE3 if you don't put this bootflag in com.apple.Boot.plist Leopard will not boot.
With mach_kernel 9.1.0 SS3 you can boot without that flag but this kernel seems to be modified to boot in 32 bits mode only.
You can verify if your system is in 32/64 bits mode using GeekBench.
The "-system=X86PC" (I thought it was "-platform=X86PC") tells Leopard that you're booting on an i386 machine so it must only load i386 code and not ppc code.
