Why would you use a dual core AMD in 32 bit mode? Just build an x86_64 kernel.
If you want to use 4GB in 32 bit mode, you *need* remapping (or you lose part of your memory). Remapping means you have MORE than 4 GB of physical address, which means you need PAE to use it at all. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
