Why would they enable something they don't need? An x86-64 kernel runs only on an x86-64 CPU, where such tricks aren't needed.
You seem to forget the 32bit emulation of x86_64 processors.
No I haven't. The 32 bit mode is for running the 32 bit kernels. The 64 bit kernels run 64 bits and don't need PAE. PAE was a hack to get around the address limitation of a 32 bit CPU. The amount of memory a 64 bit CPU can handle is more than 4 billion times greater than what a 32 bit CPU can do. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
