Astute observers will have wondered how a 32bit processor can address more than 4GB of memory. PAE is the answer. It allows 36bit addressing using 'pages' of memory. According to Torvalds, the Pentium 4 is crippled "because Intel refuses to do a 64-bit version (because they know it would totally kill ia-64)."
