This is not something I'm going to discuss further. If people want to use more than 2GB of memory, they have exactly two options with Linux: - get a machine with reasonable address spaces. Right now that's either alpha or sparc64, in the not too distant future it will be merced. - use the extra memory as a ram-disk (possibly memory-mappable, but even that I consider unlikely) This is not negotiable.
