A new patch with Davem's bugfix has been uploaded and performance seems to be quite a bit better now...
http://www.surriel.com/patches/
Unless somebody else manages to find a bug in this patch, this will be the last patch at this feature level and the next patch will contain a new feature. The new feature in question will be either the out of memory killer, or Ben LaHaise's readahead-on-VMA-level code.
(probably the OOM killer since that is a stability-related thing and the other is "just" a performance tweak)
