The actual cache line size has always been 64 bytes. The 128 number arose as an optimization for Core 2 era Intel processors. By default (configurable in BIOS), these CPUs would prefetch adjacent cache lines unintelligently. Newer CPUs prefetch more intelligently. The latest Core 2 era CPU was introduced in September 2008 (Xeon 7400 series, "Dunnington"). If you are still using one of these CPUs, especially in a multi-socket configuration, consider locating the "adjacent cache line prefetch" option in BIOS and disabling it.
