I wanted to do it with git, but gave up after some time :-(
So I finally read the commit in
question 3b7ee69d0caefbdb85a606a98bff841b8c63b97e and applied
the patch below, which reverts it up to the whitespace fixes.
And reverting it really made my brand new 2.6.28-rc2-something
work again, regarding suspend to RAM.
So consider it confirmed that this commit is guilty here.
