Issue was fixed in 2.6.28-rc3, most likely by:
commit 1f98757776eafe31065be9118db6051afcf8643c
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Sat Nov 1 10:17:22 2008 -0700
    x86: Clean up late e820 resource allocation

It turns out that my test was incorrect, so the issue is not fixed.
Not reopening the BR as there's no need to track this as a regression anymore.
