(Part of?) the according patch is this:
http://www.kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fv2.6%2Fpatch-2.6.17.4.bz2;z=17

That would be getting rid of dump file "handling" at all, I think,
since PR_SET_DUMPABLE=1 is probably _not_ wanted since it reintroduces
the problems why =2 was made before. So basically this means: No core
dumps when s{u,g}id'ing.

A quick patch is appended.
