HIGHPTE isn't recommended in general because it imposes a fairly high performance hit (even without Xen, but worse with). And, worse, at the moment I don't have any plausible fix for the bug. Its really a left-over from the days of 32-bit machines with much more than 4G of memory; these days you'd use 64-bit. J
