Ah I've heard of PAE before but never investigated it. It appears to be largely used in server architecture, so does not seem to apply to a Windows 7 32bit installation, as the list specifies that W7x86 only allows up to 4GB

@0xC0000022L to be fair, I added the license part as a edit after his comment, but due to the 4 min edit window it looks like I posted it before he posted the comment.

PAE requires page table switcheroo to work, and that is costly in terms of performance.

THat's a myth. The overhead due to PAE is tiny. And if you dislike PAE you should really hate x64, because the page table structure on x64 looks just like PAE, just with yet another table level added on top and more bits for PFNs in the PxE's.

PAE was not "removed in Windows 7 because it is no longer needed", it is still present in Windows 7 x86 - it's just there by default rather than having to be optioned in.
