This reminded me of: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=c673f1a9d994de501b674b2bb6a48bd5e912afe0 Quoting Patch description: > i386: divorce CONFIG_X86_PAE from CONFIG_HIGHMEM64G > > PAE is useful for more than supporting more than 4GB RAM.

For these reasons, the following patch divorces CONFIG_X86_PAE > from CONFIG_HIGHMEM64G. Which brings me to the point why I'm writing this mail: should we enable PAE by default after F8 is out and ship a HIGHMEM64G-Kernel instead on x86-32? Then normal users on x86-32 can benefit from NX by default. Or is that considered "not worth the trouble because we ship execshield already"? Further: Does PAE-by-default still make lots of machines unbootable (I doubt that for newer machines, as some-well-known-other-os enables PAE since its service pack 2 by default iirc)? If we suspect it still does: could we fix that by some kind of automatic "if machine is newer than ${year}" check in the kernel? Just wondering.
