If you look up the Atom E6xx CPUs (used e.g. in the Soekris net6501), that site claims that they are 32 bits only. In reality, these CPUs do support 64-bit mode, as numerous owners can testify to. As other people have said, the presence of long mode in the CPU ID flags tells the true story. -- Christian "naddy" Weisgerber naddy@mips.inka.de
