My mistake, I thought PSE-36 also pre-dated PAE but obviously I was wrong. One thing which is interesting is that "pse36" normally appears separate from "pse" in /proc/cpuinfo but doesn't appear here, just like "pae" is missing I don't see anywhere in the kernel which masks off X86_FEATURE_PAE or X86_FEATURE_PSE36 though. I guess running x86info would give the real underlying features untouched by the kernel if Bernhard wants to confirm.
