I did a grep through the kernel changelogs for this commit:

$ grep 96990a4ae979df9e235d01097d6175759331e88c *
ChangeLog-2.6.22.19:    patch 96990a4ae979df9e235d01097d6175759331e88c
in mainline.
ChangeLog-2.6.23.15:    patch 96990a4ae979df9e235d01097d6175759331e88c
in mainline.
ChangeLog-2.6.24:commit 96990a4ae979df9e235d01097d6175759331e88c

Or: this commit should have been included in kernel 2.6.24. But the
PAE memory leak I observed still occurs with 2.6.24.2. So the question
remains: is there already a fix available for the problem I observed ?
