Well, the problem was actually quite simple. I just did not use the
fstab because I thought it is ignored by the system. I did not consider
setting up an fstab file and mounting my swap partition to
/private/var/vm. Since I have done the latter, everything works
flawlessly. But good to know that Apple _is_ in fact following the
standards altho sometimes you have to tweak these. Thanks to Jayce Piel
who has also set up an excellent page on this issue on his server:
