Presumably, it would also be possible to use PSE36 in place of PAE, as with the PSE36 Ram Disk [1] model. I am not sure if this is a performance win over PAE, [1] says the OS doesn't need to be modified so it sounds like it should be, but ultimately the real fix is clearly x86_64. (And we'd have to add our own PSE36 support to the Linux kernel, at best it sounds like a lot of work for a dying architecture) [1] http://www.microsoft.com/whdc/system/platform/server/PAE/pae_os.mspx [2] http://en.wikipedia.org/wiki/PSE-36 -- John C.
